Cryptography involves creating written or generated codes that allow information to be kept secret. ... Information security uses cryptography on several levels. The information cannot be read without a key to decrypt it. The information maintains its integrity during transit and while being stored.
In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet.
Footprinting (also known as reconnaissance) is the technique used for gathering information about computer systems and the entities they belong to. ... This information is very useful to a hacker who is trying to crack a whole system.
In this mobile hacking section, you will have many softwares for mobile hacking operation, all softwares are free to use and secure
Web applications are usually accessible over the internet. This makes them vulnerable to attacks. Web application threats include SQL Injection, Code Injection, XSS, Defacement, Cookie poisoning, etc. A good security policy when developing web applications can help make them secure.
Hacking Web Servers. ... Most people think a web server is just the hardware computer, but a web server is also the software computer application that is installed in the hardware computer. The primary function of a web server is to deliver web pages on the request to clients using the Hypertext Transfer Protocol (HTTP).
Cracking a wireless network is defeating the security of a wireless local-area network. A commonly used wireless LAN is a Wi-Fi network. Wireless LANs have inherent security weaknesses from which wired networks are exempt. Wireless cracking is an information network attack similar to a direct intrusion.
Network scanning refers to the use of a computer network to gather information regarding computing systems. Network scanning is mainly used for security assessment, system maintenance, and also for performing attacks by hackers. ... Recognize available UDP and TCP network services running on the targeted hosts.
In computer science, session hijacking, sometimes also known as cookie hijacking is the exploitation of a valid computer session—sometimes also called a session key—to gain unauthorized access to information or services in a computer system.
System hacking is defined as the compromise of computer systems and software to gain access to the target computer and steal or misuse their sensitive information. Here the malicious hacker exploits the weaknesses in a computer system or network to gain unauthorized access of its data or take illegal advantage of it.
In information security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations.
In computer programming, an enumerated type is a data type consisting of a set of named values called elements, members, enumeral, or enumerators of the type. The enumerator names are usually identifiers that behave as constants in the language. An enumerated type can be seen as a degenerate tagged union of unit type.
Evading IDS, Firewalls and Honeypots. An Intrusion Detection System (IDS) is a device or software application that monitors network and/or system activities for malicious activities or policy violations and produces reports to a Management Station.
A computer worm is a type of malicious software program whose primary function is to infect other computers while remaining active on infected systems. A computer worm is self-replicating malware that duplicates itself to spread to uninfected computer
A sniff is when you take air in through your nose to smell something. Dogs sniff a lot. It's how they get to know the world. Imagine this when you see the figurative use for sniff meaning to snoop as in, "The detective was sniffing around for clues." Sniff is one of those words that sound like what they mean.
Social engineering, in the context of information security, is the psychological manipulation of people into performing actions or divulging confidential information. This differs from social engineering within the social sciences, which does not concern the divulging of confidential information.
SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution.
A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users' systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems.
A penetration test, colloquially known as a pen test, pentest or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system.
