Small Business Security

For small businesses a security strategy may consist of a firewall and anti virus software.  While that may have been adequate several years ago, a good security strategy should be multi-layered.  If your company is connected to the Internet, that alone makes you a target for hackers, network attacks, malware downloads from insecure browsing and viruses sent via email.

iT Support Squad recommends a multi-layer strategy based on Defense in Depth:
  • Blocking network based attacks
    • Examples: firewall, anti virus gateways, secure email, spam protection, and secure web filtering, intrusion detection and prevention
  • Blocking host based attacks
    • Examples: personal anti virus, personal firewalls, spy-ware removal, host intrusion prevention
  • Eliminating security vulnerabilities
    • Examples: patch configuration management and compliance, vulnerability management and penetration testing
  • Safely supporting authorised users
  • Examples: strong passwords, VPNs, secure remote access, file encryption, ID access and management
  • Tools to minimize business losses and maximize effectiveness
    • Examples: backup, log management, regulatory compliance tools
Each layer builds upon the previous one and if a layer is "skipped" then your company is vulnerable and at risk.  Ideally your company implements each of these layers for a secure network and computing environment, however, it may be cost prohibitive.

iT Support Squad can assist you in determining the best security strategy for your company that minimises the risks to your data, network and users.
