In other words, it means making sure no person or event is able to block legitimate or timely access to information.

They will be more detailed than Governing Policy and will be system or issue specific, e. It is also known as the Deming W. The added "O" stands for observation or as some versions say "Grasp the current condition.

Analyze the differences to determine their root causes. It is organized into ten major sections, each covering a different topic or area: 1. Business Continuity Planning The objectives of this section are as follows: To counteract interruptions to business activities and to critical business processes from the effects of major failures or disasters.

System Access Control The objectives of this section are as follows: 1 To control access to information 2 To prevent unauthorized access to information systems 3 To ensure the protection of networked services 4 To prevent unauthorized computer access 5 To detect unauthorized activities. System Development and Maintenance The objectives of this section are as follows: 1 To ensure security is built into operational systems; 2 To prevent loss, modification or misuse of user data in application systems; 3 To protect the confidentiality, authenticity and integrity of information; 4 To ensure IT projects and support activities are conducted in a secure manner; 5 To maintain the security of application system software and data.

Physical and Environmental Security The objectives of this section are as follows: To prevent unauthorized access, damage and interference to business premises and information; to prevent loss, damage or compromise of assets and interruption to business activities; to prevent compromise or theft of information and information processing facilities. Personnel Security The objectives of this section are: To reduce risk s of human error, theft, fraud or misuse of facilities; to ensure that users are aware of information security threats and concerns, and are equipped to support the corporate security policy in the course of their normal work; to minimise the damage from security incidents and malfunctions and learn from such incidents.

Security Organisation The objectives of this section are: 1 To manage information security within the Company; 2 To maintain the security of organizational information processing facilities and information assets accessed by third parties.

Asset Classification and Control The objectives of this section are: To maintain appropriate protection of corporate assets and to ensure that information assets receive an appropriate level of protection. Security Policy The objectives of this section are: To provide management direction and support for information security. It contains a model Information Security Policy, a model Statement of Applicability, a pre-written Information Security Manual, a Business Continuity Plan, a Service Level Agreement Template fit-for-purpose information, pre-written policies, procedures, templates and guidance.

Why Information Security is needed? The repository on a SQL Server database stores the settings, results, reports and schedules for each scan together with the relevant system configuration data.

All data contained within the repository is encrypted. Each scan engine runs vulnerability checks for each of the hosts and stores these results in a designated repository.

Hosts that are to be scanned can be specified by the user, or the scan engine can perform host discovery based upon a range of IP addresses. Weak xppassword have been cited by experts from SANS, industry, government, and academia as one of the most critical security threats to computer networks. It also checks for defaults passwords those are not changed on Windows based machines because all default and weak passwords are security threat for the confidentiality, integrity and availability of data.

It also provides options like dictionary attacks, brute force attacks and hybrid attacks to audit the weaknesses in enforced password security policy. Windows Password Auditor also has the ability to present all cracked passwords in the form of a vulnerability report so that it complies with a defined controls and organizational security policy.

The best way to discover weak passwords is through audits on a regular basis. Additional checks are required for employees taking up trusted positions. Another benefit of rotation of duties is that if an individual attempts to commit fraud within his position, detection is more likely to happen if there is another employee who knows what tasks should be performed in that position and how they should be performed. Another environment may require no authentication process and let anyone and everyone into different sections.

These electrical signals can travel a certain distance and can be contained by a specially made material, which is used to construct the control zone. As technical control for system access can be a user name password, biometrics or authentication using smartcards.

They preserve the confidentiality and integrity of data and enforce specific paths for communication to take place. They help to point out weakness of other technical controls and make the necessary changes.

More important, do NOT open any email attachment unless you are exactly sure what it is. Recently, the most common are emails that look like they are coming from ebay, paypal, citibank, etc claiming there is a problem with your account and you need to update or confirm your account info. By means of some available tools, persons other than the designated recipients can read the email contents.

This is not just for counter-terrorism reasons but also to facilitate combat against industrial espionage spying and to carry out political eavesdropping listening private information. Here, the man-in- the-middle attack modify all the email packets going to and from the mail server or gateway.

This may lead to loss, confusion, or damage to the reputation of an individual or organization. It can be accomplished from within a LAN, or from an external environment. What to do? The algorithm outputs the private key and a corresponding public key. It is then up to the business units to have plans for the subsequent functions. Security Organization Structure: To follow and maintain security of organization it is necessary to define roles and responsibilities among the staff as well as maintain flow of information.

Figure — 15 shows how should be the security organization structure. Who is governing and what are they governing. This group has the vision as to where the business is going and how technology will help it get there. There is program governance and business process governance. In most organizations, this group is called the Program or Project Committee. In some companies, the Executive and Strategic governance layers are combined.

In order to deliver services the necessary support processes must to be set up. Security policy: Adopting a security process that outlines an organization's expectations for security, which can then demonstrate management's support and commitment to security. Security organization: Having a management structure for security, including appointing security coordinators, delegating security management responsibilities and establishing a security incident response process.

Asset classification and control: Conducting a detailed assessment and inventory of an organization's information infrastructure and information assets to determine an appropriate level of security. Personnel security: Making security a key component of the human resources and business operations. This includes writing security expectations in job responsibilities IT admins and end users , screening new personnel for criminal histories, using confidentiality agreements when dealing with sensitive information and having a reporting process for security incidents.

Physical and environmental security: Establishing a policy that protects the IT infrastructure, physical plant and employees. This includes controlling building access, having backup power supplies, performing routine equipment maintenance and securing off-site equipment.

Communications and operations management: Preventing security incidents by implementing preventive measures, such as using antivirus protection, maintaining and monitoring logs, securing remote connections and having incident response procedures.

Access control: Protecting against internal abuses and external intrusions by controlling access to network and application resources through such measures as password management, authentication and event logging. Systems development and maintenance: Ensuring that security is an integral part of any network deployment or expansion, and that existing systems are properly maintained.

Business continuity management: Planning for disasters--natural and man-made--and recovering from them. Within the broad scope of auditing information security there are multiple types of audits, multiple objectives for different audits, etc. Auditing information security covers topics from auditing the physical security of data centers to auditing the logical security of databases and highlights key components to look for and different methods for auditing these areas.

All of these events have the potential to introduce a new security threat vector, and thus need to be addressed accordingly in order to comply with your legal responsibility obligations. While the repeat business is nice for us, such repetition is surely more trouble than it is worth. Manual assessments include interviewing staff, performing security vulnerability scans, reviewing application and operating system access controls, and analyzing physical access to the systems.

Systems can include personal computers, servers, mainframes, network routers, switches. What is CAAT? CAATs is the practice of using computers to automate the audit processes.
