Software Based Systems : Using Specialized Security Software Essay

Public key and private is a type of encryption technique that can be used ensuring that the communication on the network is secured. When you sending a message to someone through the network, will need to use the public key of the receiver and the receiver will use the private key to decrypt the message. This encryption will avoid unauthorised access to the message such as reading

Generally speaking, modern encryption techniques fall into one of two categories - symmetric (homogeneous) and asymmetric (heterogeneous). Symmetric encryption is a system of communication whereby both parties share the same key to encode and decode a message. The Spartan generals used this method with their scytales.

In our recent negotiation, my partner Dave and I assumed the roles of Alan Hacker, a computer software developer, and Alan Hacker’s lawyer. Being the lawyer in the negotiation my objective was to avoid litigation with my client’s partner Stanley Star and to aid in the continuation of my client’s co-owned company HackerStar. In addition, I would assist Hacker in coming to an agreement that would be satisfying for him both personally and financially. I felt that Dave and I presented a reasonable argument on Hacker’s behalf and, since I was able to apply some of our class readings during the process, I was overall pleased with the outcome.

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

Data, often referred to as plaintext, is encrypted using an encryption algorithm and an encryption key. This process generates ciphertext that can only be viewed in its original form if decrypted with the correct key. Decryption is simply the inverse of encryption, following the same steps but reversing the order in which the keys are applied (Rouse, 2014).

There’s two types used in encryption, there’s the public key which is used to encrypt the information you trying to send. There is also the private key which is used to decrypt the message. The public and private key is used in many things for example emails and telephones. The reason why it’s so important that these two keys are used is because the message you’re sending stays between you and the receiver, therefore the message will not get interrupted by an invader.

Encyption takes data and transforms it into unreadable jargon until a key is used to unlock or decrypt the data back to its original form. Due to its near infallibility, encryption is one the most best ways to secure data (Williams & Sawyer, 2015).

Encrypting files is an effective way of securing information over the internet and protect the confidentiality and integrity of data. 128-bit encryption is the mathematical equivalent of key combinations used by encryption and decryption algorithms to keep data transmission secure. The strength of a key is in the key length, and numbers of bits in a key, the longer the key the more secure or hard it will be to crack the encryption.

To understand encryption, you must place yourself into the internet of the 90’s. At the time the internet was still new, all the data could be seen and accessed easily.The problem was that anyone could access your information and read it. This was a major issue because at that time, internet privacy was almost impossible.

Encryption converts data from a readable form to unintelligible text. Only authorized users are able to convert the data back into a readable format. (Sayles & Trawick,

Establishing an effective Information Technology Security Policy Framework is critical in the development of a comprehensive security program. The purpose of the Information Security Policy Framework is to insure your organization will be able to provide the minimum security level necessary to maintain confidentiality, integrity, and availability of the information it collects and uses.

Customer Needs- Security systems are required by people to0 keep their homes safe, it gives them a sense of safety for their personal belongings, when they are away from their home.

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

Asymmetric key system (or asymmetric algorithm; public key): A cryptographic system that uses two separate keys: one key to encrypt and a different key to decrypt information. These keys are known as public and private

A threat agent is the facilitator of an attack however; a threat is a constant danger to an asset.
