pressures, organizations must perform system & security audits to enhance their systems’ comply with corporate security & IT policy/ies and at minimum avoid common downtimes. Security is even more vital now that most corporate networks also link to the Internet. Today security is not defined by a good firewall, a file server structure and an antivirus subscription. Security vulnerabilities can be derived from the most unsuspected device and/or sub-system that are connected to the organization’s network. This could be from an IP telephone set to an un-patched SQL server. ASSURANCE IN AN INSECURE WORLD
If organizations must accept that they are never totally IT stable / secure — that it is inevitable a downtime will occur or an attacker will break into the systems — can there ever be assurance? Yes there can be, in a sense. Organizations still must be prepared for downtimes/attacks. They must build networks and systems that aren’t fragile. Fragile systems are those that collapse when a single system/s and/or security weakness is propagated. Below are a few suggestions for dealing with IT / security risks in an increasingly insecure world:
• Assign an actual value to IT / security risks. This will enable organizations to tell whether they are investing rationally to minimize risks.
• Think about how the organization allocates risk. Identify the single points of failure and those that could cause catastrophic losses.
• Don't be overconfident in IT platforms / security defences. Don't assume systems are stable / secure. Encourage people to look for flaws.
• Make realistic assumptions. Organizations can’t prevent all downtimes and/or security problems. Future problems may be different than past problems.
• Minimize complexity. Isolate critical components from the rest of the network and separate high-risk data from potential threats. Avoid adding complicated software and/or system features whilst not using a single line of defence
• Invest more in evaluation than design when examining IT systems. Evaluations will point out where systems are not stable and/or secure. A hacker will invest 8/10 of his time in evaluating the system and 2/10 to attack.
• Be sceptical. Assume products and services are vulnerable. Do not rely on default and/or expected deployments.
• Plan for trouble. Focus on how the organization will react if a security breach or downtime occurs. Set up audit records and put countermeasures in place. Perform downtime / pe*******on tests.
• Use both internal and external expertise. Organizations that rely solely on their in-house staff generally fail because they cut themselves off from ideas from outside sources. A balance of in-house outsource expertise is normally the best approach.

2. THE AUDIT PROCESS
An IT audit using policy-management involves four steps:
• Choosing or setting up a policy. Many industry-standard and in-house developed methods/tools will be used to help the organization develop/put forward a policy.
• Identifying the systems to be audited. A very important phase that will provide raw but valuable data to the IT process as security administrators and auditors will be determining which policy applies to which system/s.
• Scheduling or activating a scan. During this scan, software and otherwise tools will gather data from each machine over the network. Scans can be performed interactively or scheduled to run at a particular time.
• Presenting the report. Auditors are responsible for reporting the findings and presenting the results to the management.

3. IT ASPECTS / POTENTIAL HAZARDS / IT SECURITY POLICY / SYSTEMS TO BE AUDITED

In order for a security administrator to consider the computer environment as a whole and to implement adequate procedures to safeguard this environment, formal IT Policy/ies and procedures will enable official standard against which to measure compliance. With a documented and communicated IT Policy, users cater with care important security controls such as confidentiality and passwords. This will serves to decrease the risk that an unauthorized person may gain access to the system, in which case sensitive information may be used for unauthorized purposes, or the integrity of important data may be compromised.

• Formal IT / Security Policy in place
At the beginning of this review, we’ll attempt to ensure that all of the relevant issues and business practices for live networked systems will contain details about issues such as:
• Number of users.
• Required transaction types and volumes.
• Minimum acceptable response times.
• Maximum acceptable failure rate.
• Overall availability required.
• System and user support needed.
• Access control over users and privacy controls.
• Logging of activities and system accountability.
• Data encryption. To develop a security clear IT infrastructure, ALL network devices (physical and logical) have to be closely examined with a variety of assessment tools (Interviews; Network scanning; Pe*******on tests ;) to include the following aspects at minimum:
