Quick Enrol

You Will Learn How To

  • Analyse your exposure to security threats and protect your organisation's systems and data
  • Reduce your susceptibility to an attack by deploying firewalls and data encryption
  • Assess alternative user and host authentication mechanisms
  • Manage risks emanating from inside the organisation and from the Internet
  • Protect network users from hostile applications and viruses
  • Identify the security risks that need to be addressed within your organisation

Course Benefits

In today's Internet-dependent business environment, organisations must link their systems across enterprise-wide and virtual private networks as well as connect mobile users. Each connection increases exposure to customers, competitors and hackers, magnifying vulnerability to attack. In this course, you learn how to analyse risks to your networks and the steps needed to select and deploy the appropriate countermeasures to reduce your exposure to network threats.

Who Should Attend

Those who require the fundamental skills to develop and implement security schemes designed to protect their organisation's information from threats.

Workshop Course

Workshops providing you with experience analysing system and network security, include:
  • Cracking passwords using rainbow tables
  • Scanning systems with Microsoft Baseline Security Analyzer (MBSA)
  • Ensuring trusted server access via digital certificates
  • Preventing unwanted network access with a personal firewall
  • Encrypting and signing important data
  • Exposing and rectifying communication vulnerabilities with remote hosts

"Det är inte alla IT-experter som har förmågan att lära ut till andra hur man gör. Alla Learning Tree-instruktörer jag träffat har dock både haft de rätta kunskaperna och förmågan att förmedla dem tydligt och effektivt. Eftersom de använder teknikerna i sitt eget jobb underlättar det ytterligare för dem att lära ut på rätt sätt."
