What are cyber attacks and how do you defend against them?The May 2009 ISO/IEC 27000 publication described an attack on an information or computer network as an “attempt to destroy, expose, alter, disable, steal or gain unauthorized access to or make unauthorized use of anything that has value to the organization.” ⁽¹⁾ Show The concept of a cyber attack or a computer network attack is rooted in this description. Techopedia describes a cyber attack as a “deliberate exploitation of computer systems, technology-dependent enterprises and networks.” Techopedia continues, stating that cyber attacks use “malicious code to alter computer code, logic or data, resulting in disruptive consequences that can compromise data and lead to cybercrimes, such as information and identity theft.” ⁽²⁾ It’s not just computer networks and computer information systems that are being attacked. Cyber attacks are also infamous for attacking computer infrastructure and peoples’ personal computers. In addition to cybercrime, cyber attacks can also be associated with cyberwarfare or cyberterrorism, particularly in instances when the attackers are state actors, groups or affiliated organizations. For example, in 2014 a group hacked Sony Pictures and stole troves of data, including many Sony Pictures employees’ personal information, executive salary information, copies of unreleased films, and more. The group, which is suspected to be North Korean or affiliated with North Korea, used a Shamoon wiper malware to obliterate Sony Pictures’ computer infrastructure. What are the most common types of cyber attacks?According to long-time Netwrix blogger Jeff Melnick, the ten most common types of cyber attack consist of the following examples:
For Hypertext Transfer Protocol (HTTP) transactions, where there often is a TCP connection with a client and a server, the attacker takes advantage of any weakness in the network communication protocol. By forking the TCP connection into two connections, the attacker creates one connection between the attacker and the victim, and a second connection between the attacker and the server. By using the process known as Address Resolution Protocol (ARP) spoofing, the attacker masquerades as a proxy reading and gets the victim to direct traffic through the attacker as opposed to through the normal router.
Techopedia expands on this explanation, describing a replay attack as one where an attacker detects a data transmission, then fraudulently delays or repeats it, before retransmitting it. To further expand on this explanation, replay attacks target the security protocol with data transmission replays from a different sender into the targeted receiving system.

Which of the following can be used to mitigate botnets?The best approach to protecting your website and web server from botnet attacks is to invest in an advanced anti-bot mitigation service like DataDome, that can perform real-time botnet detection.
Which of the following can be used to mitigate botnet Mcq?Explanation: The owner of botnets can control the botnet using command & control (C&C) software.
How can botnets be prevented?Establish control access to machines and systems. Controlling access to machines and systems is another effective way to keep botnet attacks at bay. Not only should you use complex passwords, but you can also deploy multi-factor authentication and controls to provide access only to authorized users.
