Hosting Your Own Game Server Securely

 

Running your own game server is a great way to play with friends on your own terms, whether it is a Minecraft world, a survival game, or a modded lobby. It also means putting a computer on the internet and inviting strangers to connect to it. Anything reachable from the internet gets scanned and tested by automated tools within hours. Here is how to host a server without handing attackers a way into your home network.

Understand Your Attack Surface

Your attack surface is every point where an attacker could try to get in. For a game server, that includes:

• The open ports that players connect through
• The server software itself and any mods or plugins
• Remote administration tools, such as an admin console or RCON
• The operating system underneath
• Your admin accounts and passwords
• Everything else on the same network as the server

Security here is mostly about shrinking that list and protecting what remains.

1. Isolate the Server

Do not run a public server on the same machine or network segment as your personal files. Put it on a separate VLAN or network segment, in a virtual machine, or in a container. If the server is compromised, the attacker lands in an isolated box with nothing valuable instead of your main PC, NAS, or work laptop. This is segmentation combined with containing the blast radius of a breach.

2. Open Only the Ports You Need

Forward only the specific port or ports the game requires, to the server's address only, and use a DHCP reservation so the address never changes. Avoid UPnP and never place the server in the router's DMZ. Use firewall rules on both the router and the server's host firewall so only the required traffic is allowed. Everything else should be blocked by default.

3. Apply Least Privilege

Never run the server as an administrator or root user. Create a dedicated, low-privilege account whose only job is running the game server, and give it access only to the server's own folder. If an attacker takes over the server process, they inherit only that account's limited rights, which makes it far harder to move deeper into the system.

4. Lock Down Remote Administration

Many servers include a remote console, and it is a prime target. Change every default password immediately, and use long, unique credentials. Do not expose the admin port to the internet. Bind it to localhost, or require access through a VPN or SSH with key-based login. Where the platform supports it, turn on multi-factor authentication for the hosting and admin accounts.

5. Keep Everything Patched

Vulnerabilities in server software are found regularly, and attackers scan for out-of-date servers. A well-known example is Log4Shell in late 2021, a flaw in a widely used logging library that let attackers run code on vulnerable systems, including many Minecraft servers. Servers that had been patched were safe.

Build a routine of vulnerability management:

• Update the server software, operating system, and dependencies regularly
• Subscribe to the game or project's security announcements
• Only install mods and plugins from trusted sources, and remove ones you no longer use, since each is extra code that could be flawed or malicious

6. Use a Secure Baseline

A secure baseline is a hardened starting configuration you apply every time. For a server, that means removing unneeded software and services, disabling unused accounts, turning on the host firewall, and using the settings the developer recommends for security. Write it down, so a rebuilt server gets the same protections as the first one.

7. Protect Against DDoS and Exposure of Your Home IP

Players who connect to a home-hosted server learn your public IP address, and a disgruntled player can flood it with traffic in a distributed denial of service (DDoS) attack that knocks your whole household offline. Options to reduce this include using a hosting provider or cloud server instead of your home connection, or placing a protective proxy or tunneling service in front of your server so your real address is not exposed. Allowlisting trusted players also limits who can connect at all.

8. Monitor and Back Up

Enable logging on the server and review it for repeated failed logins, unfamiliar admin actions, or sudden traffic spikes. Keep versioned backups of the world and configuration files, with a copy stored offline or offsite, so you can recover from corruption, a bad update, or ransomware.

Quick Checklist

1. Server isolated from personal devices
2. Only required ports forwarded, no UPnP or DMZ
3. Runs as a low-privilege account
4. Admin console protected and default passwords changed
5. Server, mods, and operating system kept up to date
6. Hardened baseline applied
7. Home IP protected from DDoS where possible
8. Logging on and backups tested

Key Takeaways

• Every internet-facing service expands your attack surface, so keep it small.
• Isolation, least privilege, and tight firewall rules limit the damage of a breach.
• Patching and careful choice of mods close the vulnerabilities attackers look for.
• Hardened baselines, monitoring, and backups make a server resilient.

Risk Assessment: Is That Cheap Game Key Worth It?

 

You find a hot new release for 70% off on a site you have never heard of. The price looks great, the checkout is quick, and a key arrives in your inbox. Is it a bargain or a trap? Answering that question properly is exactly what security professionals call risk assessment, and you can use it on any decision, from game keys to home network changes.

What Risk Assessment Is

Risk is the possibility that something bad happens, combined with how much damage it would cause. A risk assessment is a structured way to measure that so you can decide what to do about it. It starts with a few simple parts:

• Asset: something you want to protect, such as your game library, account, payment card, or PC
• Threat: something that could cause harm, such as a scammer or malware
• Vulnerability: a weakness a threat can use, such as trusting an unknown seller
• Likelihood: how probable the bad event is
• Impact: how much harm it causes if it happens

Risk is roughly likelihood multiplied by impact. A very unlikely event with a small impact is low risk. A fairly likely event with a big impact is high risk.

The Risks Behind Cheap Keys

Not every discount site is dangerous, but the discounts often come from sources that create real problems:

• Stolen or fraudulent keys. Keys bought with stolen credit cards can be revoked later when the owner disputes the charge. Your game, and sometimes your account, may be affected.
• Region-restricted keys. Keys bought cheaply in one country may be blocked in another, leaving you with a useless code.
• Account penalties. A platform may flag an account that activated a revoked or fraudulent key.
• Phishing and fake storefronts. Look-alike sites collect your card number and login details.
• Malware. Sites offering cracks, key generators, or "free" versions are a common way to spread malware. This is a classic threat vector: a path an attacker uses to reach you.
• No recourse. If the seller disappears, you have no support and may not get a refund.

Qualitative vs. Quantitative Analysis

There are two main ways to analyze risk.

Qualitative analysis uses ratings like low, medium, and high. You judge the likelihood and the impact, then rank the risk. A key from an unknown seller might be "medium likelihood, high impact," which makes it a high risk.

Quantitative analysis puts numbers on it:

• Single loss expectancy (SLE): the cost of one incident
• Annualized rate of occurrence (ARO): how often you expect it per year
• Annualized loss expectancy (ALE): SLE multiplied by ARO, the expected yearly loss

Here is an illustrative example. Suppose your game library and account are worth about $1,000, and a revoked key could get your account suspended. If the loss would be the full $1,000 and you estimate a 5% chance per year (an ARO of 0.05), then ALE = $1,000 × 0.05 = $50 per year. If buying from unofficial sellers saves you $20 a year, the expected loss is larger than the savings. The numbers are estimates, but they make the trade-off visible.

Choosing a Response

Once you understand a risk, you pick how to handle it:

• Avoid: do not take the risk at all, for example by not buying from unknown sellers
• Mitigate: reduce it, for example by buying only from reputable, authorized resellers, paying with a credit card that offers dispute protection, and checking reviews first
• Transfer: shift the cost to someone else, such as using a payment method with fraud protection
• Accept: knowingly live with it, which is reasonable for small, low-impact risks

What is acceptable depends on your risk appetite, how much risk you are willing to take, and your risk tolerance, how much variation from that you can stand. After you apply controls, the risk that remains is residual risk.

A Quick Checklist for Game Purchases

1. Is the seller an authorized retailer or the official store?
2. Is the price so low that it only makes sense if the key is stolen or restricted?
3. Does the site use HTTPS and have a real history and reviews from independent sources?
4. Is there a refund policy and a way to contact support?
5. Am I using a payment method that lets me dispute a charge?
6. Am I being asked to download anything beyond the game itself?

If the answers raise doubts, the cheap key is probably not worth the risk.

Key Takeaways

• Risk combines how likely something is with how damaging it would be.
• Qualitative analysis ranks risk by rating; quantitative analysis uses SLE, ARO, and ALE.
• The usual responses are avoid, mitigate, transfer, or accept.
• Cheap keys can bring fraud, account penalties, phishing, and malware.
• Thinking through risk first leads to better decisions, in games and in security.

Logs and Anti-Cheat: How Game Servers Spot Bad Behavior

 

Every online game has to answer one question constantly: is this player behaving like a normal player? When someone teleports across the map, hits every shot, or logs in from three countries in an hour, something is wrong. Game studios catch this with logging, monitoring, and anti-cheat systems, and the same techniques are the foundation of security operations in every industry. Here is how they work and what you can learn from them.

Why Logging Matters

A log is a timestamped record of something that happened: a login, a failed password, a purchase, a match result, a connection from a new device. On their own, logs are just text files. Together, they let defenders answer the questions that matter after something goes wrong: what happened, when, from where, and to which account.

Good logging supports three jobs:

• Detection: spotting suspicious activity as it happens
• Investigation: reconstructing what an attacker did
• Accountability: proving who did what

Without logs, a breach can go unnoticed for months. With them, defenders can often catch it within minutes.

What Game Servers Record

Typical game and platform logs include:

• Login attempts, successes, and failures, with IP addresses and device information
• Account changes such as password resets, email changes, and new payment methods
• In-game actions like movement, item transfers, and trades
• Match results and statistics
• Server performance and connection events

Each one can reveal an attack. Many failed logins from one address suggest brute force or credential stuffing. A login from a new country moments after one from your home suggests a stolen account. Items moving rapidly out of an account suggest it was taken over and is being drained.

How Anti-Cheat Detects Cheaters

Anti-cheat is a specialized form of security monitoring. It generally uses several methods together:

Signature-based detection. The system looks for known cheat programs, files, or memory patterns, similar to how antivirus identifies known malware. It is accurate against known tools but misses new ones.

Behavioral and anomaly detection. Instead of searching for a known cheat, the system learns what normal play looks like and flags statistics that fall outside it, such as inhuman reaction times or perfect accuracy. This catches new cheats, but it can produce false positives, flagging an honest player who is simply very good.

Server-side validation. The server does not blindly trust what a player's computer reports. It checks whether actions are physically possible, such as speed or position. This follows the same principle as never trusting user input.

Client-side integrity checks. Some anti-cheat software runs on the player's computer to detect tampering with the game. Some versions run with very high privileges at the operating system level. That gives strong visibility, but it also expands the attack surface, since a flaw in that software could be abused by attackers. It is a good example of a security trade-off.

Tuning and Alert Fatigue

Every detection system faces the same balance. Set the sensitivity too low and cheaters slip through, which are false negatives. Set it too high and innocent players get banned, which are false positives. Security teams face this daily. Too many low-quality alerts cause alert fatigue, where analysts start ignoring warnings and miss a real attack. Good monitoring is tuned, prioritized, and reviewed.

From Logs to Response

Large organizations collect logs from many systems into a central platform, often called a SIEM (security information and event management). It correlates events across sources, such as a failed login on one system followed by a successful one on another and raises alerts. When something suspicious is found, the response follows the same pattern as banning a cheater: investigate, confirm, contain the account or device, and fix the weakness.

Two details make logs trustworthy:

• Accurate time. Systems must keep synchronized clocks, usually with NTP, so events line up in the right order.
• Protection and retention. Logs should be stored securely, protected from tampering, and kept long enough to investigate older incidents.

What You Can Do at Home

1. Turn on login alerts for your gaming and email accounts.
2. Review the "recent activity" or "logged-in devices" page on your platforms.
3. Check your router's logs and connected-device list from time to time.
4. Keep Windows or macOS security logs and notifications enabled.
5. Treat unexpected login or password reset emails as a possible breach and change your password right away.

Key Takeaways

• Logs record events, and they are essential for detecting and investigating attacks.
• Anti-cheat combines signature, behavioral, server-side, and client-side methods.
• Detection must be tuned to balance false positives, false negatives, and alert fatigue.
• Centralized monitoring, accurate timestamps, and protected logs make incident response possible.
• Home users can use the same ideas: enable alerts and review account activity.

Defense in Depth: Security Lessons from Tower Defense Games

 

If you have played a tower defense game, you already understand one of the most important ideas in cybersecurity. No single tower stops every enemy. Fast units slip past slow towers, armored units shrug off weak damage, and flying units ignore the ground defenses entirely. You win by layering different towers so that what one misses, another catches. Security professionals call this defense in depth.

What Defense in Depth Means

Defense in depth is the practice of using multiple, independent layers of security controls so that if one fails, others still protect the system. It assumes that every control has weaknesses and that attackers will eventually find one. The goal is not a perfect wall. It is to slow attackers down, force them to defeat many different controls, and give you time to detect and respond.

The Layers, Tower Defense Style

Physical security: the map itself. Locks, cameras, and controlled access keep people away from hardware. A locked server closet or a console kept out of reach is the first line, because anyone who can touch a device can often bypass software protections.

Network perimeter: the front gate. Firewalls, intrusion prevention systems, and a properly configured router filter traffic coming in. This is your first tower, and it handles the bulk of basic threats.

Network segmentation: the winding path. Good tower defense maps force enemies along a long route past many towers. Segmentation does the same. Separate networks for gaming, work, and smart devices mean that an attacker who gets into one area cannot walk into the rest.

Endpoint security: towers at every junction. Antivirus or endpoint protection, a host firewall, and a hardened operating system protect each individual device, so a threat that gets through the perimeter still faces resistance.

Application security: upgrades. Keeping software, game clients, drivers, and firmware patched closes known vulnerabilities. In game terms, patching is your upgrade path. A tower that is never upgraded falls to the later waves.

Identity and access: the gatekeepers. Strong unique passwords, multi-factor authentication, and least privilege limit what any account can do. Use a standard account for daily activity instead of an administrator account.

Data security: protecting the base. Encryption protects data if a device is stolen, and backups protect it if something is destroyed. If everything else fails, your most valuable data is still safe and recoverable.

Monitoring and response: vision and range. Logs, alerts, and regular reviews let you see enemies coming. A tower you cannot see working is a tower you cannot trust, and a breach you never notice does the most damage.

People and policy: the player. Awareness of phishing and social engineering, plus simple household rules such as "never share verification codes," support every technical layer. Even the best defenses fail if someone hands over the keys.

Types of Controls

Security frameworks describe the controls inside each layer by their purpose, and a well-built defense uses a mix:

• Preventive: stops an attack before it succeeds, such as a firewall or MFA.
• Deterrent: discourages attackers, such as warning banners or visible cameras.
• Detective: identifies an attack in progress, such as logs and alerts.
• Corrective: limits damage and restores operations, such as restoring from backup.
• Compensating: a substitute control used when the ideal one is not possible.

Controls are also grouped by category: technical (software and hardware), managerial (policies and risk decisions), operational (day-to-day procedures and people), and physical (locks and barriers).

Why One Layer Is Never Enough

Imagine relying only on your router's firewall. A phishing email never touches the firewall, since the victim clicks the link from inside. A stolen password defeats a network perimeter completely. A hardware failure bypasses every digital control. Each threat targets a different gap, which is why layers with different strengths matter.

Building Your Own Layers at Home

1. Secure and update your router, and segment gaming and smart devices.
2. Keep operating systems and game clients patched.
3. Turn on MFA and use a password manager.
4. Run endpoint protection and use a standard account day to day.
5. Keep versioned backups with an offline copy.
6. Review router logs and account login alerts occasionally.

Key Takeaways

• Defense in depth uses multiple independent layers so one failure is not fatal.
• Layers span physical, network, endpoint, application, identity, data, monitoring, and people.
• Use a mix of preventive, detective, deterrent, corrective, and compensating controls.
• Assume any single control can fail, and design so the next layer catches the threat.

Zero Trust for a LAN Party: Never Trust, Always Verify

 

A LAN party is one of the best parts of gaming: friends, consoles, laptops, and a pile of cables in your living room. It is also a security headache. Every guest brings devices you did not buy, did not patch, and cannot vouch for. One laptop with malware, or one friend who clicked a bad link last week, can put everything on your home network at risk. Zero Trust is a security model built for exactly this situation, and you can use it at home.

The Old Model: Castle and Moat

Traditional network security works like a castle. A strong perimeter, usually the firewall, keeps outsiders out, and anyone inside is trusted. Once a device joins your Wi-Fi, it can often see your PC, your NAS, your printer, and your smart TV.

That approach has a big flaw. If an attacker gets past the perimeter, or a guest brings an infected device inside it, they can move freely. This is called lateral movement, and it is how a single compromised device turns into a full breach.

The Zero Trust Model

Zero Trust drops the idea that being "inside" means being safe. Its core principles are:

• Never trust, always verify. Every user, device, and request must prove itself, every time.
• Least privilege. Each device gets access only to what it needs and nothing more.
• Assume breach. Design as if an attacker is already present, so the damage stays small.

Zero Trust is not one product. It is a design approach that combines identity checks, device health checks, and tight network controls.

How It Works in Practice

Enterprise Zero Trust architectures are often split into two parts:

• The control plane makes the decisions. A policy engine evaluates each request using signals such as who is asking, what device they are on, whether it is patched, and where it is connecting from. A policy administrator carries out the decision.
• The data plane carries the actual traffic. A policy enforcement point sits in the path and allows or blocks the connection based on the decision.

The idea of adaptive identity matters here too: trust is not permanent. A request is judged on current context, and access can be reduced or cut off if something changes.

Applying It to Your LAN Party

You do not need enterprise gear. Most home routers and access points can do a lot of this.

1. Segment guests from everything important. Put guests on a separate guest network or VLAN. Your personal PC, NAS, work laptop, and smart home devices stay on a different segment that guests cannot reach. This is network segmentation, and it limits lateral movement.

2. Turn on client isolation. Many access points have a setting that stops guest devices from talking to each other. Players only need to reach the game, not each other's file shares. If a game needs peer-to-peer play, allow only that traffic.

3. Allow only what is needed. Instead of open access, write firewall rules for the specific ports and services your games use. Everything else stays blocked. This is least privilege applied to the network.

4. Verify the person and the device. Give guests a unique passphrase, ideally one you change after the event, instead of reusing your main Wi-Fi password. Ask guests to update their operating system and run antivirus before joining. This is a simple version of a device posture check.

5. Make access temporary. Create the guest network just for the event and remove it afterward. Time-limited access is a Zero Trust habit that shrinks your exposure window.

6. Watch the network. Check your router's connected-device list during the event. If something unfamiliar appears, remove it. Logging and monitoring support the "assume breach" mindset.

Key Takeaways

• Castle-and-moat security trusts everything inside the network, which makes lateral movement easy.
• Zero Trust verifies every user, device, and request, grants least privilege, and assumes breach.
• Segmentation and client isolation keep a compromised guest device from reaching your important systems.
• Short-lived access and basic monitoring reduce risk even without special equipment.

Protecting Your Gaming Account: MFA vs. Passkeys

 

Your gaming account is worth more than you think. It holds years of purchases, rare skins and items, saved payment methods, and friends lists that attackers love to abuse. Hijacked accounts get stripped of inventory, sold, or used to scam your friends. The best defense is strong authentication, and in 2026 you have more options than ever. Here is how the main ones compare.

Why Passwords Alone Fail

Most gaming account takeovers do not involve clever hacking. Attackers use credential stuffing: they take passwords leaked in old breaches and try them on game platforms, hoping you reused one. Others send phishing links that mimic a login page. A password is only one factor, something you know, and anyone who learns it can use it from anywhere.

Multi-factor authentication (MFA) adds a second proof from a different category:

• Something you know: a password or PIN
• Something you have: a phone, authenticator app, or security key
• Something you are: a fingerprint or face scan

Even if a password is stolen, the attacker still needs the second factor.

Comparing the Options

SMS text codes. Better than nothing, but the weakest MFA option. Attackers can perform SIM swapping, convincing a carrier to move your number to their SIM, and then receive your codes. Texts can also be intercepted or phished. Use SMS only when nothing else is offered.

Authenticator apps (TOTP). Apps like Microsoft Authenticator or Google Authenticator generate a six-digit code that changes every 30 seconds. The code is created on your device and never travels over the phone network, so SIM swapping does not work. The weakness is phishing: if you type the code into a fake login page, the attacker can use it immediately.

Push notifications. You tap "Approve" on your phone. This is convenient, but attackers exploit it with MFA fatigue, spamming approval requests until a tired user taps yes. If you get a prompt you did not trigger, always deny it and change your password.

Hardware security keys. A physical USB or NFC key using the FIDO2 standard. The key checks the website's real domain before responding, so a fake login page gets nothing. This is among the strongest options available. The trade-off is cost, and you should register a backup key in case you lose one.

Passkeys. Passkeys replace the password entirely. When you register, your device creates a key pair: a private key that stays on your device and a public key stored by the service. To sign in, your device proves it holds the private key after you unlock it with a fingerprint, face scan, or PIN. Nothing secret is ever sent to the server, so there is no password to leak in a breach, and passkeys are tied to the real website, so phishing pages cannot capture them. Passkeys can sync across your devices through a password manager or your phone's platform account.

Quick Ranking for Gamers

1. Passkeys or hardware security keys: strongest and phishing-resistant
2. Authenticator app: strong, free, and widely supported
3. Push notifications: convenient, but watch for fatigue attacks
4. SMS codes: weakest, but still better than no MFA

Practical Steps You Can Take Today

• Turn on MFA for every platform: Steam, Xbox, PlayStation, Nintendo, Battle.net, Epic, and your email account. Email matters most, because password resets go there.
• Use passkeys where offered. Many major platforms now support them.
• Save your recovery codes somewhere safe and offline. They are your way back in if you lose your phone.
• Use a password manager so every account has a unique password.
• Never share verification codes. No legitimate support agent or friend needs your code. Treat any request for one as a scam.
• Review logged-in devices in your account settings and remove any you do not recognize.

Key Takeaways

• A password alone is not enough, and reused passwords make credential stuffing easy.
• MFA combines factors from different categories: something you know, have, or are.
• SMS is the weakest MFA method; authenticator apps are better; security keys and passkeys are strongest.
• Passkeys remove the password and resist phishing.
• Keep recovery codes safe and protect your email account first.

Don't Lose Your Save Files: The 3-2-1 Backup Rule

 

You've put 200 hours into a save file. Then one morning your drive dies, a bad update corrupts your profile, or ransomware locks everything with a ransom note on the screen. If your only copy was on that machine, those hours are gone. The 3-2-1 backup rule is a simple, proven way to make sure that never happens to you, and it's the same rule IT professionals use to protect business data.

What 3-2-1 Means

• 3 copies of your data: the original plus two backups.
• 2 different types of media, such as your internal SSD plus an external hard drive or NAS, so a single type of failure can't take out everything.
• 1 copy offsite, such as cloud storage or a drive kept at a relative's house, so a fire, flood, or theft at home doesn't destroy every copy.

Each part covers a different failure. Multiple copies protect against accidents and corruption. Different media protect against hardware failure. Offsite storage protects against physical disaster.

Why Cloud Saves Aren't a Backup

Many platforms sync your saves to the cloud, and that feels like a backup. It's really synchronization. If a save is corrupted or deleted locally, the sync can faithfully copy that damage to the cloud. Some games also overwrite the cloud copy with a newer, broken one. A true backup keeps older versions you can roll back to.

The Ransomware Angle

Ransomware encrypts your files and demands payment for the key. Backups are the best defense because you can restore without paying. But modern ransomware also hunts for backups. If your external drive is always plugged in, or a network share is always mounted, the malware can encrypt those too.

This is why many security teams use the extended 3-2-1-1-0 rule:

• The extra 1 is a copy that is offline or immutable, meaning it can't be changed or deleted, even by an infected computer.
• The 0 means zero errors after you verify the backup.

At home, this can be as simple as an external drive you unplug after each backup, or a cloud service with versioning and a retention window.

Types of Backups

• Full: a complete copy of everything. It's the simplest to restore but takes the most time and space.
• Incremental: copies only what changed since the last backup of any type. It's fast and small, but restoring requires the last full backup plus every incremental after it.
• Differential: copies everything changed since the last full backup. It grows over time, but restoring needs only the full backup plus the latest differential.

A common home approach is a full backup weekly with incrementals daily.

RPO and RTO in Plain English

Two terms matter in professional resilience planning:

• Recovery Point Objective (RPO): how much data you can afford to lose, measured in time. If you back up nightly, your RPO is about 24 hours. You could lose a day of progress.
• Recovery Time Objective (RTO): how long you can afford to be down. If it takes six hours to reinstall and restore, your RTO is six hours.

If losing a day of progress would be painful, back up more often. If you need to be playing again quickly, keep a restore process that's fast and documented.

Test Your Restores

An untested backup is a hope, not a plan. Backups can fail silently because of full drives, expired credentials, or corrupted files. Every so often, restore a few files, or one game's save folder, to a different location and confirm everything opens. Add this to your routine and you'll catch problems while you still have the original.

A Simple Gamer Setup

1. Original saves and configs live on your main PC.
2. Automatic backup to an external drive on a schedule.
3. A versioned cloud backup as your offsite copy.
4. Unplug the external drive when it isn't backing up.
5. Test a restore every month or two.

Key Takeaways

• Follow 3-2-1: three copies, two media types, one offsite.
• Cloud sync is not the same as backup. Keep versioned copies.
• Keep at least one copy offline or immutable to survive ransomware.
• Know your RPO and RTO so your schedule fits your needs.
• Test restores regularly.
•
