Day-352: What is Access Control?

__ACL stands for Access Control List and it is one of the most fundamental components of information security. It is made up of some 'rules' that would allow or deny access to a computerized environment.For example, you are a manager of an exclusive club and have made a list of club's members and selected few guests who are invited to a party. When you strictly follow the LIST you have made up of your members & guests, then only those on this list are allowed in the doors. Right?Access Control List is very much similar to this. It enable you to ensure that, unless the proper credentials are presented by the device or user, it cannot gain access in your environment, e.g., your network or system.At the fundamental level, there are two basic kinds of ACLs:➤ Filesystem ACLs➤ Networking ACLs👉 What are the important components of ACLs?There are several components of ACL which are critical to its function:➤ Sequence number➤ ACL name➤ Remark➤ StatementStatement is not remarks or description, as given above. With a statement, you either permit or deny a source using a 'wildcard mask' or address. A wildcard mask dictates which elements of an IP address can be examined by a system.➤ Network protocolThis section can be used to permit or deny certain networking protocols, such as IP, Internetwork Packet Exchange (IPX), TCP, ICMP, UDP, or others.➤ Source or destinationIt defines the destination or source IP address as an 'address range' or a single IP. It can also allow all addresses.➤ LogThere are devices that can maintain a log when they find ACL matches. Quite handy for you!➤ Other criteria of advanced ACLs_Do you want to become a Skilled-Cybersecurity Professional 🕴🕴🕴.Here is the gateway ⛩  https://luminisindia.com/goehm How to perform a 🔥🔥PENTESTING🔥🔥???🎯🎯 A Pentesting Mini Project🎯🎯https://www.youtube.com/watch?v=84gNIEmCEAA If you find the video content informative, please Like thevideo and 📣📣📣 share with your friends.Help your friends to understand cybersecurity.
