Stonesoft Warns Flame, Stuxnet, Duqu Still Not as Dangerous as Conventional SCADA and ICS Attacks
Security gaps, advanced evasion techniques, denial of service attacks pose bigger threats
Helsinki, Finland – 20 June, 2012 Despite widespread warnings around Flame, Stuxnet and Duqu viruses, Stonesoft advises organizations relying on SCADA and industrial control system (ICS) networks to be vigilant against conventional network threats. These threats pose a far greater threat to SCADA and ICS network security, and include gaps in security infrastructure, advanced evasion techniques (AETs) and simple denial of service attacks. Stonesoft is a global provider of proven, innovative network security solutions, including IPS, firewall/VPN, SSL-VPN and remote cloud access.
“Our advice to ICS and SCADA network managers is to be informed of new threats like Flame, but be especially vigilant against the more conventional, widely understood threats. In all likelihood, a simple denial-of-service attack has a better chance of wreaking havoc on their network than Stuxnet or Duqu. It’s important they don’t drop the ball as the game advances,” said Olli-Pekka Niemi, Vulnerability Expert at Stonesoft.
Stonesoft advises organizations deploying SCADA and ICS networks to protect their networks in the following ways:
By monitoring all data traffic, and only allowing it into the network if it’s safe, IPS devices keep the network clear of malicious traffic. If the device detects malware attempting to enter the network, it will automatically sever the data connection and prevent network penetration. IPS devices can also facilitate virtual patching, which protects vulnerable servers in between scheduled maintenance windows.
AET detection capabilities.
Hackers have always used evasion techniques to skirt IPS protection. Most recently, they have developed advanced evasion techniques (AETs) that combine and modify traditional evasions. The result is that an organization can be re-exposed to old threats as well as susceptible to new ones.
Sophisticated threats like AETs and advanced persistent threats (APTs) require advanced security mechanisms – namely normalization. Using advanced normalization, the IPS interprets the data traffic and assembles the packets in the same manner as the end system. This allows the IPS to detect malicious code hidden in the data flow. Normalization is nothing new, but the ability to perform it without sacrificing network performance has traditionally been a challenge. SCADA and ICS networks must ensure traffic normalization is both powerful and realistic in real-world traffic scenarios.
Most network security solutions deployed in industrial environments are hardware-based, making them difficult, time-consuming and expensive to update. Software-based solutions eliminate these hurdles, eliminate human error and improve security effectiveness.
