Malware: This is a malicious program or software that disrupts or damages the computer. There are three types of malware. The expectations, skills and development required for a professional specialism or area of practice along with details on progression through different roles.

The third element (of three) when encrypting data: one takes an Encryption Algorithm and combines it with a Cryptographic Key to transform Plain Text into Cipher Text.

The state of having been awarded a recognised qualification by a professional body that is the holder of a Royal Charter. Escort all guests within the building. This may not match your company’s culture or be realistic, but it can certainly help minimize social engineering risks. The act of actively engaging to comply with the requirements of an organisation along with other requirements such as behaving appropriately in society in general or engaging in Continuing Professional Development. Software whose source code is released to the public at no charge, and which can be reused by anyone under the terms of a liberal set of licensing rules.

Internet is a means of connecting a computer to any other computer anywhere in the world via dedicated routers and servers. 3. Internet Protocols Availability: The principles of availability assert that systems, functions, and data must be available on-demand according to agreed-upon parameters based on levels of service. An instance in which an encryption or Hash Function produces the same output for two or more given sets of input. Training or education that is oriented toward teaching specific skills to a high level of ability rather than covering a wide range of skills to a lesser extent. Success is measured by evaluating the student's ability to carry out specific tasks to a given standard. Where you have systems configured in a High Availability setup, a Failover is where you switch from the active element to the standby element.

Exploit– A malicious application or script that can be used to take advantage of a computer’s vulnerability. The level of difficulty in breaking a cryptographic system: a high cryptographic strength means the cipher is very difficult to break. The principle of assigning every user with only the privileges they actually need to do their job, and no more. Largely synonymous with Professional Development, CPD is the common term for the measure of the ongoing development undertaken by an individual to maintain a current and relevant level of practice. "CPD credits" are the common units of measurement: one credit generally equates to one hour of attendance at a seminar or conference, for example.Use safe connections. Never access sensitive information over free public Wi-Fi and consider avoiding using such Internet access altogether, especially from any device on which you perform sensitive activities or access sensitive information.The connection provided by your cellular service is likely far more secure than any public Wi-Fi, and such connections can usually be shared by multiple devices if you turn on your phone’s “mobile hotspot” feature. A parameter used in a cryptographic algorithm: you apply the algorithm to the Plain Text and the key, and the result is the Cipher Text. If a different key is used for the same Plain Text, the result will be a different Cipher Text. CompTIA training products use a multi-faceted approach, are designed to follow exam objectives and offer a variety of options to meet the needs of different types of learners at different stages of their training. So no matter what method you choose, you know that what you’re studying is what you’ll see on the test – and what you need to know to help keep organizations secure. The most commonly used family of Hash Functions; unlike Message Digest 5 there are no known vulnerabilities in the more recently devised SHA algorithms.
