Security and information protection

Lately, not a week goes by without news of a hack of some kind – usually involving stolen data or operational disruption.

Domain traders Netfleet and even Symantec are two companies who suffered compromises this month, with one of Netfleet’s databases (which included customer names and details) exposed, and the source code for Symantec’s PCAnywhere software apparently stolen from an Indian military server.

Together, the two events demonstrate that hackers are actively going after targets both big and small.

How can your business protect itself?

In addition to ensuring that your firewall, authentication and software-patching regimes are secure and up-to-date, one of the best tools in any arsenal is a proactive network monitoring solution.

Proactive solutions deploy a range of smart defences, including:

  • Network Behavioural Analysis (NBA) and Active Threat Feed (ATF). NBA and ATF learn what’s ‘normal’ on your network, and alert you to strange network activity indicating the presence of malware and data leakage.
  • Intrusion detection. Unauthorised access often goes unnoticed, but proactive monitoring can turn the tables by alerting you to an intruder before they can do any damage.
  • Protocol detection. Peer-to-peer traffic is often a sign of unwanted activity on a business network. Network monitoring solutions can put a stop to it before your business is exposed to unwanted (and frequently illegal) content.
  • Compliance. HIPAA, PCI, and SOX compliance regimes require a range of security systems and processes. Proactive monitoring solutions assist by ensuring that deployed systems are functioning as they should.
  • Asset protection. By actively scanning your network for zero day attacks, dark address space, protocol misuse, unauthorised access and phishing attacks, active monitoring allows you to protect your important information assets and customer data.
