Simple Cybersecurity Tips from CISA to Protect Your Business

/0 Comments/in /by

The Cybersecurity and Infrastructure Security Agency (CISA) recommends businesses keep it simple and focus on these four critical actions now:

  • Teach Employees to Avoid Phishing – Phishing happens when criminals trick employees into opening malicious attachments or sharing personal info. Implement training to teach employees how to identify and report suspicious activity.
  • Require Strong Passwords – This is one of the easiest ways to protect your business from criminals who might otherwise access your accounts by guessing or using automated hacking programs.
  • Require Multifactor Authentication – Use more than a password when signing into accounts, such as a texted code, authenticator app or biometrics – to make them much safer than a password alone! MFA protects accounts by requiring additional authentication to prevent access by others.
  • Update Business Software – Defects in software, routers, VPNs and apps can give criminals an opening to your accounts. Software manufacturers publish patches, but you must install them to be protected! Don’t use outdated software. Keep business software up to date.

6 Best Practices for a Stronger Cybersecurity Posture

How to Fortify Your Digital Fortress

Effective cybersecurity is not a “set it and forget it” panacea but an active, ongoing process. To establish a robust security foundation, your IT team must diligently implement and maintain these critical best practices:

1. Restrict Administrator Privileges

Limit administrator access on user devices. This simple step can thwart many attacks that rely on users inadvertently running malicious software. Without admin rights, users can’t install unauthorized programs, significantly reducing your attack surface.

2. Stay Current with Patches

Keeping software up to date is one of the most cost-effective security measures. Enable auto-updates where possible and prioritize vulnerabilities listed in CISA’s Known Exploited Vulnerabilities Catalog. Remember, many successful attacks exploit known vulnerabilities that have not yet been patched.

3. Implement and Verify Backup Systems

Don’t fall victim to ransomware due to inadequate backups. Regularly schedule backups for all critical systems and, crucially, test both partial and full restorations. Develop a comprehensive backup strategy, including frequency (continuous, hourly, weekly) and a detailed restoration plan.

4. Encrypt Laptop Drives

While smartphones and Chromebooks typically come with built-in encryption, Windows and Mac laptops often require manual configuration. Given the frequency of laptop theft or loss, ensuring your entire fleet has encrypted drives is essential for data protection.

5. Enforce Multi-Factor Authentication (MFA)

Don’t rely on user compliance alone. Implement technical controls to mandate MFA across your organization. Regularly audit for non-compliant accounts, paying special attention to new hires and staff who’ve recently changed devices.

6. Prioritize MFA for Admin Accounts

System administrators are prime targets for cybercriminals. Surprisingly, Microsoft reports that only about half of Azure Active Directory global admins use MFA. Make it a non-negotiable policy for all admin accounts to use MFA, as compromised admin credentials can lead to catastrophic breaches.

By consistently applying these practices, you’ll significantly enhance your organization’s cybersecurity posture, making it far more resilient against common attack vectors.

Your organization’s Voice Communications need to be protected too. Make sure your systems are secure. Contact TCI at (703) 321-3030 or GetHelp@tcicomm.com.
