What do you mean by security? Discuss in brief access control list
Solution
Security, in the context of information technology, refers to the measures taken to protect systems, networks, and data from digital attacks. These measures are designed to prevent unauthorized access, use, disclosure, disruption, modification, or destruction of information. Security involves both physical and digital measures, ranging from training people to recognize phishing emails to protecting data centers from physical threats.
An Access Control List (ACL), on the other hand, is a list of permissions attached to an object. This object can be a file, a directory, or a piece of hardware like a router. The ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject (a user or group of users) and an operation (read, write, execute, etc.).
The purpose of an ACL is to provide a means of enforcing security policies on a system. For example, an ACL could be used to restrict read and write access to a sensitive file to only certain users. Alternatively, an ACL could be used to restrict network access to a particular IP address or range of IP addresses.
In summary, security is a broad term that encompasses all the measures taken to protect systems and data, while an Access Control List is a specific tool used to enforce security policies on a system.

Access control is a method of limiting access to a system or to physical or virtual resources. It is a process by which users can access and are granted certain prerogative to systems, resources or information. Access control is a security technique that has control over who can view different aspects, what can be viewed and who can use resources in a computing environment. It is a fundamental concept in security that reduces risk to the business or organization. To establish a secure system, electronic access control systems are used that depend on user credentials, access card readers, auditing and reports to track employee access to restricted business locations and areas. These systems include access control panels to prohibit entry to sensitive areas like alarms and lock down areas to prevent unauthorized access or operations. Access control systems perform identification, authentication, and authorization of users and entities by evaluating required login credentials that may include passwords, pins, bio-metric scans or other authentication factors. There is multi-factor authentication which requires two or more authentication factors which is often an important part of the layered defense to protect access control systems. Authentication Factors:Password or PINBio-metric measurement (fingerprint & retina scan)Card or Key
