It’s that special time of the year when individuals across various regions eagerly anticipate reunions with loved ones and a chance to unwind.
Regrettably, this period is also marked by a surge in online threats as malicious entities tend to exploit the reduced network surveillance during the holidays. For instance, incidents of ransomware attacks typically witness a significant rise during this season.
To assist you in navigating this period securely, here are some simple yet effective strategies to enhance the security of your network while you enjoy a well-deserved break.
For a comprehensive collection of guidelines to safeguard your network from ransomware and other threats, make sure to download our detailed guide on this subject.
1. Ensure Your Network Infrastructure is Updated
Before you embark on your holiday break, verify that all your network infrastructure has been equipped with the most recent firmware updates. These updates frequently contain crucial security patches for identified vulnerabilities or strengthen security measures.
For Sophos Firewall users, ensure that all your firewalls are upgraded to v21.
If you belong to our clientele still utilizing the soon-to-be obsolete XG Series devices, place an order for the new XGS Series before your departure. The upgrade process is straightforward, with substantial cost savings available – plus, by upgrading early, you can overlap your licenses.
A new backup/restore assistant has been introduced to facilitate the upgrade to your new XGS Series device, complete with comprehensive port-mapping options. Additionally, we’ve recently unveiled a fresh series of desktop XGS models boasting heightened performance and efficiency levels.
If you have other externally-facing infrastructure like a VPN concentrator or WAF, remember to keep them updated as well.
2. Deactivate Non-Essential Systems during the Break
Any system exposed to the internet presents an attractive target for malevolent actors seeking to infiltrate your network. If you have internet-facing systems, particularly accessible via RDP or VNC, deactivate these systems over the holidays.
As you plan for the upcoming year, consider implementing Zero Trust Network Access (ZTNA) to furnish robust, cutting-edge protection for these systems and bolster your security posture. ZTNA permits secure access solely for authenticated users, rendering your networked applications and systems invisible to potential attacks.
If ZTNA isn’t in place and you need to remotely access any systems during the holidays, restrict access to LAN only and utilize remote access VPN – disable any port forwarding or NAT regulations on your firewall. This advice also applies to any user portals that you may have set up – it’s advisable to disable them temporarily during the holidays.
3. Guarantee Secure Authentication with MFA
Attackers frequently exploit weak credentials through brute force login attempts, especially during the festive season. Ensure all systems within your network are adequately safeguarded with robust passwords and multi-factor authentication (MFA). These measures drastically decrease the risk of unauthorized access, enhancing your network’s security.
