Enterprise Security Systems Audit
Audit of security and control systems can be internal and external. Internal audit activities are conducted by the managers or appointed employees of this organization. An external audit is conducted by employees of an independent company with whom an agreement was concluded to provide such services under standard control programs. It is accepted to single out the overall PURPOSES OF AUDITING:
Analysis of existing risks that are associated with possible threats to the security level at the facility (or relative to specific resources);
Assessment of the current state of the security complex and the level of security;
Localization of specialized places in the system;
Evaluation of equipment for compliance with technical requirements and established standards in a specific area;
Development of recommendations on the introduction of new technologies and improving the quality of the security line as a whole or each mechanism separately.
In addition to the above objectives, a number of additional tasks are established before the audit:
Development of a security policy at the facility, which is fixed in special documentary acts;
Setting goals and control over their implementation by responsible employees (for example, security services);
Training users of security systems;
Participation in investigations in the event of incidents, etc.
Stages of providing audit services regarding security systems
Conducting an assessment of the state of the security system of an object includes several successive stages:
- Initiation of an audit;
- The collection of necessary information and the implementation of comprehensive measures aimed at obtaining information that is relevant to reality;
- Analysis of the data;
- Development and provision of recommendations for improving the quality of the security system installed in the controlled territory;
- Providing reporting documentation.
Initiation of verification of the current state of the security system is carried out by the facility manager or a person who has the necessary authority.
What does an expert check of the security complex include?
Today, monitoring of the internal control system has become quite relevant. Performing monitoring and analyzing actions allows obtaining information on the state of the security complex at the present time. Having received certain information, the head can take measures to improve the quality of the protective line and increase the level of security of the facility. Despite the fact that many companies have their own security service, a side view and an assessment of the condition of the equipment will reveal the shortcomings in the operation of the mechanisms and correct them.
An object security audit, as a rule, includes a number of actions:
- Assessment of the quality of work and technical characteristics of devices that complete the security system;
- Analysis of the quality of technical lines;
- Assessment of the effectiveness of the internal routine installed at the facility;
- Verification of compliance with all established safety rules by employees of the enterprise (organization or institution);
- Assessment of the effectiveness and quality of work of a security unit or a private security department;
- Development of conceptual approaches to improving the work of the defense line;
- Providing advice and recommendations regarding the personal or public safety of entities;
- Preparation of a report and transfer of factual documents to the head or authorized person.
Assessment of the state of information security
Currently, one of the main areas of audit is the assessment of the security status of information systems. In the age of electronic technology, information systems contain a lot of personal data of subjects, as well as confidential information. Therefore, first of all, it is necessary to take care of the information security at the facility. To determine the level of security of information data, certain criteria and standards are established.
The control of the information security system should be carried out at the highest level and have a sufficient degree of protection against information leakage and its subsequent use for illegal purposes. There are several types of audit of information security lines:
- Compliant with established standards and requirements.
Active audit services are the most common in the field of information security systems. All verification actions are carried out from the point of view of the so-called attacker who has sufficient knowledge in the field of computer technology. To perform the verification, specialized software is used. Qualified specialists collect information about the current state of the information security line by modeling various network situations. In case of detection of the possibility of leakage of personalized information, the auditor offers various solutions to improve the existing security complex. Some companies provide proprietary software that allows you to establish the necessary degree of information protection, but without appropriate certification this method may be questionable in terms of effectiveness.
Expert audit consists in comparing the current state of the security complex and the established standards, first of all, ISO 27001. The most common way to obtain information during an expert assessment is to interview employees and decision-makers. Based on the results of an expert assessment, changes can be made to the existing security system by installing additional equipment or software. In the case of an inadequate level of information protection, the auditor may propose the installation of a new complex, taking into account all necessary requirements.
Auditing operations for compliance with the standards consist of checking and evaluating the current state of devices and mechanisms, their technical characteristics, and work efficiency. After collecting information, the auditor reconciles the received data with the established requirements. The report contains mandatory references to regulatory documents. Typically, this type of audit is conducted when certification or licensing is required.
