In the end, IT security is all about safeguarding the most important assets of a firm. The help of a corporation includes its people, property, and data. These assets are safe because of the efforts that have been made. Policies, procedures, approaches, methods, solutions, strategies, activities, and gadgets are all included in these tools. Firewalls and monitoring systems are two examples.
When it comes to setting security measures, there is no room for error. The initial step in risk management is often to identify the organization’s overall IT security strategy. These control goals, declarations of how the organization intends to manage risk adequately, are finally defined. Ensuring that only authorized personnel have access to databases and data records, for example, is a critical control goal. However, “we have a reasonable degree of trust in the operational integrity of vital systems and infrastructure.”
If you are going to put up security measures, it is essential to know why you are doing it first. This is one of the easiest ways to categorize controls (physical, technological, or administrative).
Types of Security Controls
There are three types of control types which include physical, technical, and Administrative. Unauthorized access to physical places, systems, or assets may be restricted or detected via physical controls. Everything from guards to barricades to badges to biometric controls to CCTVs to motion sensors and sprinklers is included in the package. Additionally, temperature and humidity controls are incorporated into the system.
Hardware or software controls may be employed to safeguard assets (sometimes referred to as logical controls). Authentication, firewalls, antivirus software, intrusion detection systems (IDS), and intrusion prevention systems (IPS) are the most prevalent security solutions (ACLs).
Administrative controls are the policies, procedures, and standards that specify how an organization’s employees and commercial activities should be conducted. Team member hiring and firing, equipment or Internet use, physical access to buildings, job separation, data categorization, and audits are just a few examples of when these policies might be used. In many cases, administrative actions include security awareness training for staff.
Functions that can be Controlled
To prevent illegal behavior, preventative measures are used. Physical controls include fences, locks, and alarm systems, as well as firewalls and antivirus software. Data categorization, the division of duties, and audits are all examples of administrative controls.
It is a detective control when measures or solutions are employed to discover and warn of undesired or illegal behavior, either while it is happening or after it has happened. Physical sensors, such as door sensors and fire alarms, may notify security employees, police officers, or system administrators of suspicious activity. It is not simply honeypots and intrusion detection systems (IDS) that may be used to protect against cyberattacks.
After an unlawful or unwelcome behavior, a corrective control is any activity performed to repair harm or restore resources and capabilities to their pre-incident status. Restarting or halting a process are some examples of technical corrective measures that may be used. An example of administrative correctional control is the establishment of a crisis response strategy.
What is the Purpose of Security Control?
Security measures are an excellent way to decrease company risk. As a precautionary step, security measures are put in place. To measure the effectiveness of security control, it must be classified by the kind of security event. As a starting point, below are some of the most often used categories: Preventive control aims to keep anything wrong from happening.
After the incident, detective controls are used to investigate. The purpose of deterrent measures is to discourage criminals from committing their crimes. Compensation controls are employed when the central control cannot be implemented. Corrective measures are put in place after an occurrence
It is not an easy task to implement the necessary controls. A risk profile allows firms to highlight the potential costs of negative impacts and the resources needed for control. To accomplish “defense-in-depth,” several security methods might be implemented. “Defense-in-depth” is a typical method employed in cyber security. Your systems will remain safe even if one layer of defense fails to stop a threat.
To keep systems and people safe, cyber security programs need to invest in a wide variety of technologies and procedures to deal with a wide range of threats. As far as preventing viruses and malware from infecting PCs and servers, endpoint detection and response solutions are the finest on the market today. It would help if you utilized an IPS or a SIEM to safeguard your network in real-time. Technology may be used to assure safety.
To decrease the risk of malfunctions and vulnerabilities in hardware and software, logic controls are used. Automated software applications have been deployed and configured to protect these assets. Encryption is an excellent example of this kind of technological control. As well as Intrusion Detection Systems and Intrusion Prevention Systems (IPS).
