Dos attack
A DOS attack is designed to deny legitimate users access to a resource by overwhelming it with requests. There are two main types: a basic DOS attack from a single host, and a distributed DOS (DDOS) attack from multiple compromised machines targeting the same victim. To prevent DOS attacks, organizations can install security patches, use intrusion detection systems to identify illegal activities, configure firewalls to block traffic from attackers, and use access control lists on routers to limit network access and drop suspicious traffic.
Identifying potential security risks
Potential security risks include spam, which sends unwanted advertising and phishing emails; adware, which tracks private information to show targeted ads and is sometimes downloaded unknowingly; spyware, which secretly installs to collect third-party user information like a Trojan horse; and worms, which rapidly copy themselves over networks without changing files.
Network security (syed azam)
:- Network security is protection of the access to files and directories in a computer network against hacking, misuse and unauthorised changes to the system.

Cryptography techniques allow for message confidentiality, authentication, and integrity. Symmetric key cryptography uses a shared secret key where the sender and receiver both know the key. Public key cryptography uses key pairs where one key is public and one is private. RSA is an example of an asymmetric encryption algorithm that uses a public/private key pair based on the difficulty of factoring large numbers. Message integrity is ensured through techniques like digital signatures that authenticate the source and content of messages.

The WAN2 default route is the backup route. We only need to enable route failover monitoring on the primary route (WAN1 default route) to detect if it fails over and use the backup WAN2 route instead. Since the WAN2 route is only used if the primary fails, we don't need additional route monitoring configured on it.

Routing algorithm
The network layer is responsible for routing packets from the source to destination. The routing algorithm is the piece of software that decides where a packet goes next (e.g., which output line, or which node on a broadcast channel).For connectionless networks, the routing decision is made for each datagram. For connection-oriented networks, the decision is made once, at circuit setup time.
Routing Issues
The routing algorithm must deal with the following issues:
Correctness and simplicity: networks are never taken down; individual parts (e.g., links, routers) may fail, but the whole network should not.
Stability: if a link or router fails, how much time elapses before the remaining routers recognize the topology change? (Some never do..)
Fairness and optimality: an inherently intractable problem. Definition of optimality usually doesn't consider fairness. Do we want to maximize channel usage? Minimize average delay?
When we look at routing in detail, we'll consider both adaptive--those that take current traffic and topology into consideration--and nonadaptive algorithms.

Block ciphers like DES encrypt data in blocks and are based on the Feistel cipher structure. DES encrypts 64-bit blocks using a 56-bit key and 16 rounds of encryption. Modern cryptanalysis techniques like differential and linear cryptanalysis use statistical analysis to reveal weaknesses in block ciphers, though DES remains relatively secure against these attacks. Careful design of block ciphers, including aspects like non-linear substitution boxes and complex key scheduling, aims to provide security against cryptanalysis.Viewers also liked (20)

It ensures only authorized users can access network resources and data through authentication methods like usernames and passwords. Network security is needed because increased Internet usage has led to more hackers and attacks, putting networking systems and stored data at risk of viruses, delays, modifications or identity theft. Various security measures can help, such as antivirus software to detect malware, data loss prevention to restrict data sharing, email security to filter viruses and information leaks, and mobile security like antivirus to safeguard devices.

Malware comes in many forms and can damage computers in several ways. It is designed to spread without permission and perform unwanted tasks. Common types of malware include viruses, trojans, worms, spyware, and ransomware. Malware spreads through emails, websites, removable drives, and social networks. It can steal personal information, encrypt files until payment is made, and turn computers into bots. Users should protect themselves by installing antivirus software, practicing caution online, and scanning for malware regularly.
Viruses, worms, and trojan horses
A computer virus attaches to code or files and spreads when the infected file is run, potentially corrupting or deleting files. A worm replicates itself across a network without needing an infected file, consuming bandwidth. A Trojan horse appears benign but hides malicious code. Security procedures include plans and testing to address threats, and antivirus software detects and removes viruses, worms and Trojans, requiring frequent updates. Data encryption and firewalls can also help protect networks and traffic through ports.

Security
- 1. NETWORK SECURITY • It Protect the usability, reliability, integrity, and safety of your network and data. • Effective network security targets a variety of threats and stops them from entering or spreading on your network. • Many network security threats today are spread over the Internet. • Network Security - measures to protect data during their transmission
- 2. The most common threats include: • Viruses, worms, and Trojan horses • Spyware and adware • Zero-day attacks, also called zero-hour attacks • Hacker attacks • Denial of service attacks • Data interception and theft • Identity theft
- 3. • Network security is accomplished through hardware and software. Software must be constantly updated and managed to protect you from emerging threats. Hardware usually consists of many components. Ideally, all components work together, which minimizes maintenance and improves security.
- 4. Examples SOFTWARE : • Anti-virus and anti-spyware • Firewall, to block unauthorized access to your network HARDWARE : • Intrusion prevention systems (IPS), to identify fast-spreading threats • Virtual Private Networks (VPNs), to provide secure remote access
- 5. THREATS • With an increasing amount of people getting connected to networks, the security threats that cause massive harm are also increasing. • Network security is a major part of a network that needs to be maintained because information is being passed between computers,devices,etc and is very vulnerable to attack..
- 6. • Over the past five years people that manage network security have seen a massive increase of hackers and criminals creating malicious threats that have been pumped into networks across the world.
- 7. The biggest network threats: • Viruses and Worms • Trojan Horses • SPAM • Phishing • Packet Sniffers • Maliciously Coded Websites • Password Attacks • Hardware Loss and Residual Data Fragments • Shared Computers • Zombie Computers and Botnet
- 8. Virus & Worm • A Virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. • Viruses can cause a huge amount of damage to computers. • A worm is similar to a virus but a worm can run itself whereas a virus needs a host program to run. • Solution: Install a security suite, such as Kaspersky Total Protection, that protects the computer against threats such as viruses and worms.
- 9. Trojan Horse • A Trojan Horse is “a program in which malicious or harmful code is contained inside apparently harmless programming or data in such a way that it can get control and do its chosen form of damage, such as ruining the file allocation table on your hard disk. • Solution: Security suites, such as Norton Internet Security, will prevent you from downloading Trojan Horses
- 10. SPAM • SPAM is “flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. • Solution: SPAM filters are an effective way to stop SPAM, these filters come with most of the e-mail providers online.
- 11. Phising • Phishing is “an e-mail fraud method in which the perpetrator sends out legitimate-looking emails in an attempt to gather personal and financial information from recipients. • Solution: Similar to SPAM use Phishing filters to filter out this unwanted mail and to prevent threat.
- 12. Password Attackers • Password attacks are attacks by hackers that are able to determine passwords or find passwords to different protected electronic areas. • Many systems on a network are password protected and hence it would be easy for a hacker to hack into the systems and steal data. This may be the easiest way to obtain private information because you are able to get software online that obtains the password for you.
