“Web Menace” is not a commonly used term, and it’s unclear what exactly it refers to. However, there are several types of online threats that could be considered a menace to users on the web. Here are a few examples:
- Malware: Malware is short for “malicious software,” and it refers to any software designed to harm a computer system or steal data. Malware can be delivered through malicious websites, email attachments, or downloads from untrustworthy sources.
- Phishing: Phishing is a type of social engineering attack where scammers impersonate a trusted source (such as a bank or a social media platform) in order to trick people into giving up sensitive information like passwords or credit card numbers.
- Cyberbullying: Cyberbullying is the use of technology to harass, embarrass, or threaten someone. This can take many forms, including spreading rumors online, posting embarrassing photos, or sending threatening messages.
- Online scams: Online scams are schemes designed to trick people into giving away money or personal information. These can take many forms, such as fake job offers, lottery scams, or romance scams.
- Hate speech and misinformation: While not necessarily a direct threat to individuals, hate speech and misinformation can create a toxic online environment that can lead to real-world harm. Hate speech can contribute to the spread of prejudice and discrimination, while misinformation can lead people to make bad decisions or take dangerous actions.
(b) Give the difference between host based security and
Host-based security and perimeter security are two different approaches to protecting computer systems and networks from cyber threats. The main difference between them lies in where they focus their efforts.
Host-based security focuses on securing individual computer systems or hosts (such as servers, laptops, or desktops). This approach involves installing security software on each host to monitor and control access to resources, detect and respond to security events, and enforce security policies. Host-based security measures include things like antivirus software, firewalls, intrusion detection systems, and access control mechanisms. The idea is to protect the individual hosts from attacks that originate both from within and outside the network.
Perimeter security, on the other hand, is focused on securing the boundary or perimeter of the network. This approach involves deploying security measures such as firewalls, intrusion prevention systems, and virtual private networks (VPNs) at the network perimeter to prevent unauthorized access to the network and protect against external threats. Perimeter security measures are intended to stop threats before they reach the internal network.
(c) Explain different classes of attacks
In internetwork security, there are several different classes of attacks that malicious actors can use to compromise the security of a network. Here are some of the most common:
- Denial-of-Service (DoS) attacks: This type of attack is designed to overwhelm a network or system with traffic or requests, making it unavailable to legitimate users. DoS attacks can be accomplished using various methods such as flooding the network with traffic, sending malformed packets, or exploiting vulnerabilities in network devices.
- Man-in-the-middle (MitM) attacks: MitM attacks involve intercepting communication between two parties and tampering with it. An attacker can use this technique to eavesdrop on sensitive data, modify messages, or inject their own malicious content into the communication.
- Password attacks: Password attacks involve attempting to guess or crack a user’s password. These attacks can be accomplished using techniques such as brute force, dictionary attacks, or social engineering.
- Malware attacks: Malware refers to any software designed to harm a computer system or steal data. Malware attacks can take many forms, such as viruses, worms, trojans, or ransomware.
- Phishing attacks: Phishing attacks are a type of social engineering attack where an attacker sends a fraudulent message (such as an email or a website) that appears to be from a trusted source in order to trick the user into giving up sensitive information.
- SQL injection attacks: SQL injection attacks involve inserting malicious code into a website or application’s database queries in order to extract or modify sensitive data.
- Cross-site scripting (XSS) attacks: XSS attacks involve injecting malicious code into a website in order to steal data or take control of a user’s session.
- Buffer overflow attacks: Buffer overflow attacks involve exploiting a vulnerability in software or hardware that allows an attacker to overwrite memory and execute arbitrary code.
