Geopolitical tensions ensure that 2017 will be another big year for state-sponsored cyber attacks. The lethality of state-sponsored attacks derives from their ability to bypass security point products by combining device, network and data center vulnerabilities into an integrated assault. Another aspect of state-sponsored cyber attacks is their willingness to patiently creep from organization to organization to get to their target.
Irrespective of the lethality of state-sponsored cyber attacks, it is a mistake to think that there is no way to stop them. If your organization has something of value to a foreign government here are five cyber attack counter-measures you should be implementing.
Verify User Identity
Phishing to steal credentials is the #1 technique used by foreign governments to gain access to sensitive data. Why? It works. The bigger an organization, the greater the number of supply chain partners, the easier it becomes for cyber attackers to steal credentials.
The foundational security control to stop credential theft is 2 factor authentication. To make it less painful, you can extend the session timeout to a full workday. To protect more sensitive business critical apps, consider a certificate-based VPN that binds the user identity to their device. While it is possible to steal a certificate, as soon as you have 2 connections from the same cert you instantly know there’s a breach.
Check Device and Server Software
Right after identity theft, malware is the next favorite cyber attack technique. Installing malware on user devices and Internet accessible servers has become commonplace today. There’s now a robust international marketplace for zero-day attacks and server exploits.
Malware detection software has greatly improved in recent years so there’s no reason not to implement it. Code signing has been around for a while but IT organizations don’t like setting up PKI services to generate and verify digital certificates. However this is a critical control for any large organization.
Match Authorization to Role
The OPM cyber attackers utilized non-active contractor account to gain access to the data center. Unfortunately, most organizations maintain non-active accounts for tax purposes even thought users don’t need access to the data center.
Make sure the authorization level matches the role of the user. If you need to keep identities active for tax or retirement purposes, consider migrating non-active accounts to externally hosted identity services and allowing access only to partitioned services.
Protect Data Encryption and Virtual Desktops
Many IT managers assume that by encrypting data or putting it behind a virtual desktop they are safe they are safe from theft. Unfortunately, most data encryption systems automatically decrypt data for authorized users. Additionally, virtual desktop solutions are vulnerable to the same server exploits and data center attacks as regular PCs.
To protect against a state-sponsored cyber attack, data encryption and virtual desktop solutions need the same protections against credential theft and lateral movement that Internet accessible systems have. Implement access controls and network partitions to protect high value data encryption and virtual desktops.
Partition Supply Chain Resources
Most Fortune 500 companies have outsourced some aspect of their mission critical operations to a supply chain partner. Unfortunately, when partner personnel have all the same internal access as employee’s traditional perimeter security systems are of little value. It gets even worse when one considers that most outsourcing companies outsource their activities to other outsource companies.
Partition your data center so resources accessed by supply chain partners have no lateral access to sensitive data. One strategy that has been successfully used is migrate partner apps to a public cloud and utilize a secure application-layer connection back to the data center. This way if there is a breach, it’s contained to a public cloud.
We can’t stop foreign governments from attacking the US but we can stop the attacks from being successful! We now have enough data on their techniques to design counter-measures. We need to implement them.
