Guarding the Hoop: Cybersecurity’s Frontline

In the high-stakes game of cybersecurity, the offense is relentless. As IT and cybersecurity professionals, we’re constantly fending off invisible adversaries, striving to keep our hoop – our data – secure. But what if I told you that you could fortify your defenses and cover 85% of all potential attacks with just five key controls? Let’s dive into this cybersecurity slam dunk.

Imagine you’re the coach of a world-class basketball team. Your team is your network, your playbook is your software, and your hoop is your data. The opposing team? They’re the cyber threats, constantly attacking, trying to score a basket against you. Now, as a coach, you wouldn’t send your team out onto the court without a strategy, would you? Of course not. You’d have a game plan, a strategy to defend your hoop and keep the opposing team at bay. The same applies to cybersecurity.

 

Game Plan

So, what’s our game plan? It’s a five-part strategy, each part as crucial as the other, working together to defend our hoop. Let’s break it down:

 

1. The Roster: Inventory of Authorized and Unauthorized Devices

Think of your network as your team. Just as a coach needs to know each player’s strengths and weaknesses, you need to know every device that’s connected to your network. This includes the star players (authorized devices) and the benchwarmers (unauthorized devices). Unauthorized devices are like uninvited players who’ve snuck onto the court. They can disrupt your game plan and pose significant security risks. This is where a comprehensive inventory of all devices comes into play.

 

The Game Plan for Devices:

Draft Your Team: Start by creating a dynamic list of all devices connected to your network. This includes everything from servers and desktop computers to mobile devices and IoT gadgets. This is akin to drafting your team. You need to know who you’re working with to effectively strategize and plan your defense.

Keep Your Roster Updated: Just as a basketball team’s roster may change throughout the season, so too can your network’s device landscape. New devices may be added, old ones may be retired, and some may be temporarily benched. Regularly update this list to ensure it accurately reflects your current device landscape. This could be a weekly or monthly check, depending on the size and dynamics of your organization.

Monitor Your Team: Implement a system that alerts you when an unauthorized device connects to your network. This could be an automated alert system that sends you an email or a push notification whenever a new device is detected. This is like having a vigilant coach who notices when an uninvited player tries to join the game.

Run Regular Drills: Regularly test your alert system to ensure it’s working as expected. This could involve connecting an unauthorized device to your network and checking if the alert system responds appropriately. Just as basketball teams run drills to keep their skills sharp, regular testing helps ensure your alert system is ready for the real game.

Have a Game Plan for Uninvited Players: Develop a protocol for dealing with unauthorized devices. This could involve immediately disconnecting the device, investigating how it connected in the first place, and strengthening your defenses to prevent future incidents. Just as a coach wouldn’t let an uninvited player disrupt the game, you shouldn’t let an unauthorized device compromise your network.

 

2. The Playbook: Inventory of Authorized and Unauthorized Software

Every team has a playbook, and in our case, it’s the software running on our devices. Just as a basketball coach needs to know every play in their team’s playbook, you need to know every piece of software in your network. Unauthorized software is like a rogue play that can lead to a security fumble. It can introduce vulnerabilities and provide an avenue for cyber threats to infiltrate your network.

 

The Game Plan for Software:

Draft Your Playbook: Start by creating a comprehensive software inventory that includes all applications installed on your devices. This is akin to drafting your playbook. You need to know what plays (software) you have at your disposal to effectively strategize and plan your defense.

Keep Your Playbook Updated: Just as a basketball team’s playbook may evolve throughout the season, so can your software landscape too. New software may be installed, old ones may be uninstalled, and some may be updated. Regularly update this list to ensure it accurately reflects your current software landscape. This could be a weekly or monthly check, depending on the size and dynamics of your organization.

Monitor Your Plays: Implement a system that alerts you when unauthorized software is installed. This could be an automated alert system that sends you an email or a push notification whenever a new software installation is detected. This is like having a vigilant coach who notices when a rogue play is introduced.

Run Regular Drills: Regularly test your alert system to ensure it’s working as expected. This could involve installing unauthorized software on one of your devices and checking if the alert system responds appropriately. Just as basketball teams run drills to keep their skills sharp, regular testing helps ensure your alert system is ready for the real game.

Have a Game Plan for Rogue Plays: Develop a protocol for dealing with unauthorized software. This could involve immediately uninstalling the software, investigating how it was installed in the first place, and strengthening your defenses to prevent future incidents. Just as a coach wouldn’t let a rogue play disrupt the game, you shouldn’t let unauthorized software compromise your network.

 

3. The Defense: Secure Configuration for Hardware and Software

In basketball, a strong defense is the backbone of any team. It’s the wall that stands between the opposing team and your hoop. In our world of cybersecurity, this translates to secure configurations for all hardware and software across devices. These configurations are like your defensive strategies, designed to keep cyber threats at bay.

 

The Game Plan for Secure Configuration:

Set Your Defensive Strategy: Establish a secure configuration baseline that outlines the minimum security settings for all your devices. This could include settings related to password complexity, screen lock timeouts, and software updates. Just as a basketball team has a defensive strategy that every player knows and follows, your network should have a secure configuration baseline that all devices adhere to.

Regularly Review Your Defense: Regularly check that all devices adhere to this baseline. This could be done through automated compliance checks or manual audits. Just as a basketball coach regularly reviews their team’s defense to ensure it’s effective, you should regularly check that your devices are securely configured.

Monitor Your Defense: Implement a system that alerts you when a device deviates from this baseline. This could be an automated alert system that sends you an email or a push notification whenever a non-compliant device is detected. Just as a basketball coach keeps a close eye on their team’s defense during a game, you should monitor your devices to ensure they remain securely configured.

Adjust Your Defense as Needed: If a device is found to be non-compliant, take immediate action to bring it back in line with your secure configuration baseline. This could involve updating its settings, patching its software, or even taking it offline if necessary. Just as a basketball coach might adjust their defense in response to the opposing team’s offense, you should be ready to adjust your device configurations in response to security threats.

Train Your Team: Provide regular training for your staff about the importance of secure configurations and how to maintain them. This could involve educating them about the latest cybersecurity threats, teaching them best practices for device configuration, and updating them on any changes to your secure configuration baseline. Just as a basketball team regularly practices their defense, your staff should regularly practice maintaining secure configurations.

 

4. The Offense: Continuous Vulnerability Assessment and Remediation

In the game of cybersecurity, a good offense is a proactive one. Just as a basketball team continually assesses its opponents to identify weaknesses and exploit them, we must regularly conduct vulnerability assessments to stay ahead of the game. These assessments help us identify and patch up our own weaknesses before they can be exploited by cyber threats.

 

The Game Plan for Vulnerability Management:

Regular Training Sessions: Schedule regular vulnerability assessments for your network. This is akin to a basketball team holding regular training sessions to keep their skills sharp and ready for the next game. Depending on the size and complexity of your network, these assessments could be done monthly, quarterly, or annually.

Identify and Prioritize Weak Spots: Just as a basketball team analyzes their performance after each training session to identify and prioritize areas for improvement, you should prioritize and remediate identified vulnerabilities based on their severity. This could involve patching software, updating configurations, or replacing outdated hardware.

Keep Score: Implement a system to track the remediation process. This is like a basketball coach keeping score of each player’s performance to track progress over time. This could be a simple spreadsheet that lists all identified vulnerabilities, their severity, and the status of remediation efforts. Or it could be a dedicated vulnerability management tool that automates the tracking process.

Adjust Your Game Plan: In basketball, a good coach adjusts their game plan based on their team’s performance and the opponents they’re facing. Similarly, after each vulnerability assessment, review your findings and adjust your cybersecurity strategy as needed. This could involve updating your device and software inventories, adjusting your secure configuration baseline, or revising your admin privileges.

Stay on the Offense: In basketball, a good offense keeps the pressure on the opposing team, preventing them from gaining the upper hand. Similarly, in cybersecurity, regular vulnerability assessments keep the pressure on cyber threats, helping you stay one step ahead.

 

5. The Coach: Controlled Use of Admin Privileges

Every basketball team needs a coach, someone who calls the plays, guides the team, and maintains order. Now, imagine if every player started calling the plays. Chaos would ensue. The same applies to admin privileges in the realm of cybersecurity. Admin privileges grant powerful access rights, and if they fall into the wrong hands, it can lead to a serious security breach.

 

The Game Plan for Admin Privileges:

Assign Your Coaches: Limit the number of users with admin privileges to only those who absolutely need them. This could be a handful of IT staff or key personnel. Just as a basketball team has a limited number of coaches, your network should have a limited number of admins. This reduces the risk of admin privileges being misused or falling into the wrong hands.

Regularly Review Your Coaching Staff: Regularly review and update the list of users with admin privileges. This could be done on a monthly, quarterly, or annual basis. Just as a basketball team might change its coaching staff from time to time, your list of admins might need to be updated as personnel change.

Monitor Your Coaches: Implement a system to monitor the use of admin privileges. This could involve auditing admin actions or setting up alerts for unusual admin activity. Just as a basketball coach’s decisions are scrutinized and analyzed, the actions of your admins should be monitored to ensure they’re in line with your cybersecurity strategy.

Have a Game Plan for Time-outs: Develop a protocol for when an admin’s actions raise a red flag. This could involve temporarily suspending their admin privileges, investigating suspicious activity, and taking corrective action if necessary. Just as a basketball coach might call a time-out when the game isn’t going as planned, you should be ready to hit the pause button when an admin’s actions seem out of line.

Train Your Coaches: Provide regular training for your admins. This could involve educating them about the latest cybersecurity threats, teaching them best practices for managing admin privileges, and updating them on any changes to your cybersecurity strategy. Just as a basketball coach needs to stay updated on the latest coaching strategies, your admins need to stay updated on the latest cybersecurity strategies.
