Ditch the Breach: NCSC Urges Shift from SSLVPN to IPsec by 2025 for Enhanced Cyber Safety

Say goodbye to SSLVPN, folks! The Norwegian Cyber Security VIPs are urging a switcheroo to IPsec by 2025. Why? Because SSLVPN’s more hacked than a Hollywood blockbuster. Get ready to embrace those IKEv2 vibes! #CyberSecuritySwitcheroo

Hot Take:

It seems the Norwegian NCSC is serving a technology eviction notice: SSL VPN, pack your bags, you’ve overstayed your welcome! With vulnerabilities being as popular in SSL VPNs as cat videos are on the internet, the NCSC is pushing everyone to switch to the cybersecurity equivalent of a fortress – IPsec with IKEv2. They’re not just suggesting a change; they’re practically shouting “Get out before you get hacked!” from the digital rooftops.

Key Points:

  • Norwegian NCSC advises ditching SSLVPN/WebVPN for IPsec with IKEv2 to avoid being the low-hanging fruit for cyber baddies.
  • Organizations in critical infrastructure have until the end of 2024 to make the switch or face the wrath of potential breaches.
  • SSL VPN has been as secure as a screen door on a submarine, giving hackers a field day with numerous vulnerabilities.
  • Interim measures include VPN activity logging, geofencing, and blocking the digital dark alleys of the internet like Tor and VPN services.
  • SSL VPN’s lack of standards has created a hacker’s playground, with exploits running as rampant as squirrels in a nut factory.
Cve id: CVE-2024-20353
Cve state: PUBLISHED
Cve assigner short name: cisco
Cve date updated: 04/24/2024
Cve description: A vulnerability in the management and VPN web servers for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to incomplete error checking when parsing an HTTP header. An attacker could exploit this vulnerability by sending a crafted HTTP request to a targeted web server on a device. A successful exploit could allow the attacker to cause a DoS condition when the device reloads.

Cve id: CVE-2024-20359
Cve state: PUBLISHED
Cve assigner short name: cisco
Cve date updated: 04/24/2024
Cve description: A vulnerability in a legacy capability that allowed for the preloading of VPN clients and plug-ins and that has been available in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary code with root-level privileges. Administrator-level privileges are required to exploit this vulnerability. This vulnerability is due to improper validation of a file when it is read from system flash memory. An attacker could exploit this vulnerability by copying a crafted file to the disk0: file system of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the affected device after the next reload of the device, which could alter system behavior. Because the injected code could persist across device reboots, Cisco has raised the Security Impact Rating (SIR) of this advisory from Medium to High.

SSL VPN, You're the Weakest Link, Goodbye!

The Norwegian cybersecurity cheerleaders are rooting for IPsec with IKEv2, which, unlike the swiss cheese security of SSL VPNs, offers a more robust and less forgiving platform for secure remote access. This recommendation is like choosing a bank vault over a piggy bank to protect your gold coins.

Migration Migraine or Security Serenity?

Transitioning to IPsec with IKEv2 might seem as fun as a root canal, but the NCSC is adamant that the sweet relief of improved security is worth the pain. They've laid out a roadmap that includes reconfiguring your digital defenses and waving a final goodbye to SSL VPNs by blocking their traffic like an unwanted ex at a wedding.

A Temporary Band-Aid

For those who can't just flip a switch and enter the safe haven of IPsec with IKEv2, the NCSC is offering some interim security hygiene tips. It's like knowing there's a hole in your boat but using duct tape until you can get to shore to fix it properly.

SSL VPN's Bug Bonanza

SSL VPN has been as secure as a celebrity's phone number at a fan convention. Vulnerabilities have been popping up like mushrooms after rain, with Chinese hackers and ransomware gangs taking full advantage. These cyber pests have been gnawing away at networks, making a strong case for the NCSC's recommendation.

Global Consensus on IPsec

It's not just Norway waving the IPsec flag; the USA and UK have been singing its praises too. This isn't just a regional trend; it's a global cybersecurity fashion statement, and everyone's expected to dress accordingly.

When Standards Are Not Standard

The major issue with SSL VPN is that it's more diverse than a United Nations potluck, with every manufacturer doing their own thing. This has led to a smorgasbord of bugs that hackers relish. It's time for a more standardized approach, and IPsec with IKEv2 is strutting down the cybersecurity runway.

SSL VPN's Hall of Shame

From the Chinese Volt Typhoon hacking group to the Akira and LockBit ransomware, SSL VPN's vulnerabilities have been a VIP pass for hackers into corporate networks. It's been exploited more times than a loophole in tax law, and the NCSC has had enough.

Cisco's ArcaneDoor to Trouble

Even Cisco, the heavyweight champion of networking equipment, wasn't immune to the SSL VPN curse. They've been dealing with the 'ArcaneDoor' campaign, where attackers had a field day with two zero-days, leaving Cisco scratching their heads on how the intruders got in. It's like finding out someone broke into your high-security mansion, and you don't even know which window they pried open.

In conclusion, if you're using SSL VPN, it's time to listen to the cybersecurity experts and jump on the IPsec train. It's leaving the station, and you don't want to be left on the platform when the cybercriminals arrive.
