Different Types of Attacks

Encryption is the conversion of electronic data into another form, called cipher text, which cannot be easily understood by anyone except authorized parties. The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. Modern encryption algorithms play

These attacks can be extremely damaging to one’s intellectual properties (information, money, etc) as well as a concern for personal safety. The key to stopping or minimizing these attacks is to learn what these attacks are and how they are executed to really create an effective plan to stop unnecessary losses.

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

The aim of this document is to provide an overview on the various cryptographic technologies in use today and what the future might hold. The document will cover the following subjects:

Within this essay the issues to be discussed are problems about technology. Information technology is very important in today’s world and is used daily by many people all across the continents. Information technology has its pros and cons like other technology does, but one of the major problems are security and privacy. The main issue of this topic would be cyber threats to computer networks. Examples are threats involving denial-of-service attacks, malicious software, sniffers and more.

Computer security is a very important topic in today’s world. One does not have to look far to read about data breaches, DDoS attacks, or other computer related crimes. When we think of cybercrime, we usually envision the Hollywood portrayal of technical hackers typing vigorously and wearing dark sunglasses. However, in reality, hacking tends to be much less glamorous. Actually, one critical element is often overlooked by the general public and movies alike; yet, every security professional knows, people are the weakest link, when it comes to security. In fact, “as part of a demonstration at the 2010 Def Con hacking conference, large corporations were subject to social engineering techniques. The result was alarming: 96% of employees contacted by phone or email disclosed confidential information…” (Ricart). In this paper, I will discuss the concept of social engineering: what it is, the types of attacks, the framework used in carrying out said attacks, and lastly, I will address countermeasures to mitigate the risk.

Since the inception of IEEE 802.11i in 2004, users and IT administrators have been able to improve the security of their wireless networks by taking advantage of protocols like CCMP, which is an algorithm designed to provide authentication and encryption. With CCMP, wireless networks can be secured with 128-bit AES encryption, provided by the Counter Mode component of CCMP. The CBC-MAC mode component is what provides the authentication mechanism.

A hacker’s possibility of acquiring access into a target system are affected by element like model and configuration of the intended system, the level of expertise of the hacker and the first level of access acquired (Murphy, 2015). The most harmful form of denial of service attacks are attacks spread, where a hacker employs software distributed over a number of users’ systems over the internet to cause a cohesive denial of service attacks from several sources.

Encryption, also known as cryptography in the modern world, is the process of securing communication in the presence of third parties. Encryption is used to convert plain text data into unintelligible or useless ciphertext, and is used by many big institutions such as the government and businesses. My references discuss about why it is important that we learn about how to use encryption effectively, and how we can learn from previous methods of encryption. I will highlight what and how encryption has historically been used. My goal of this essay is to prove why we need to continue developing stronger methods of encryption.

Today, cryptography is used to provide secrecy and integrity to our data, and both authentication and anonymity to our communications.

Symmetric encryption is the earliest and widely popular encryption technique. This technique uses a secret key which can be a string of words, numbers which are randomly selected to effect confidentiality. The secret Key is applied on the original message to change the content into a cipher. The modification of the message to the cipher might be a simple reordering of the message letter sequence to complex alterations. With the help of the secret key the sender and the recipient can encrypt and decrypt messages respectively.

The message to be stored in the database is converted to cipher text using encryption algorithm and key. The resulting cipher text is then saved in database. When the user needs to get the actual message, he/she decrypts the cipher text with decryption algorithm and the key [3]. Random keys are generated in encryption process and same keys are used to decrypt the data. The security solely depends on the choice of encryption algorithm, key size and how the algorithm is implemented. If any of these criteria goes wrong, it can cause adverse effects in the security of data.

Another form of attacks is that which the attacker knows personal information regarding the target and hence formulates an email disguising it to be a familiar person. This is a method that has been used by many attackers and can be evidenced by the iCloud leak of celebrity photos. The attacker knew the sensitivity of the celebrity privacy, and thus they had to react by clicking the email to secure their sites. Most victims fall for this trick because they tend to fall for emails they assume to be from a known person. For example, an attacker can send an email claiming it’s from a colleague asking the target to confirm attendance to a birthday party (Wong, 2012). Upon clicking on the link, the target is redirected to another site. When targets respond to the trick, attackers then use the obtained data and information to blackmail and even embarrass the target. Some criminals monetize their prize not to expose the hacked information.

Cryptography is the practice and study of techniques for secure communication in the presence of third parties. The art of protecting information by transforming it (encrypting it) into an unreadable format is called cipher text.

A PC attack may be characterized as activities coordinated against PC frameworks to disturb gear operations, change transforming control, or degenerate put away information.
