Cybersecurity For Dummies (For Dummies (Computer/Tech))

Product Information

A file on a computer that the user thinks has been deleted but which probably hasn't: unless you specifically use the "secure delete" function if there is one, deleting a file usually just leaves it there but takes its entry out of the directory. Very useful if you delete something by mistake as you can get utilities to recover "deleted" files, but less useful if you lose your disk because anyone else can also get utilities to recover "deleted" files.

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. This new training course ties nicely in with the general idea behind our new e-book: providing basic information to non-techies and techies alike. To “tech” things up a little bit we added a video about VPN and connecting to unknown WiFi networks since people tend to be out of the office a lot these days.

A Brief Overview of CompTIA Security+

A standard that has been tailored to cater for the specific requirements of an organisation whilst still upholding all of the core general requirements of the standard.

Worms: These are standalone programs that run independently and infect systems. For example, W32.Alcra.F is a worm that propagates through network share devices. Instructor-Led Training which is conducted on-line via videoconferencing software rather than with the trainer and students in a physical classroom. Online Instructor-Led Training became particularly popular in 2020 as a result of the Coronavirus pandemic. Where you have systems configured in a High Availability setup, a Failover is where you switch from the active element to the standby element.In February, this year, CloudFlare, a global internet infrastructure enterprise, released a note about a bug that is causing random leakages from its cloud platform. The "edge" of a system or network, where it connects to another system or network. For example, the firewall providing connectivity between the Local Area Network and the internet is part of the Boundary. Training or education that is delivered by the student accessing the materials via a computer or similar device (such as a tablet) rather than by interacting with an instructor. CBT is not Online Instructor-Led Training as there is no interaction with a human teacher.

Virus: A computer virus is a malicious code that replicates by copying itself to another program or document and changes how a computer works. The virus requires someone to knowingly or unknowingly spread the infection without the knowledge or permission of a user or system administrator. An example of a virus is the Melissa virus. Training or education in which the student dictates the schedule and pace of the material. This is commonly achieved where the learning materials are paper- or computer-based, with the student free to undertake each element when he or she wishes. Now that you’ve reviewed the exam objectives and have an idea of what you need to prioritize, it’s time to study. eLearning A system that makes requests to a server on behalf of the client - useful because there is no direct end-to-end connection between the client and the server, thus reducing the risk of something nefarious at one the server from directly infecting the other.

Become cyber secure

Accurate means, for example, that the data is never modified in any way by any unauthorized party or by a technical glitch. Complete refers to, for example, data that has had no portion of itself removed by any unauthorized party or technical glitch. Monitor and secure hybrid environments, including cloud, mobile, Internet of Things (IoT) and operational technology The level of difficulty in breaking a cryptographic system: a high cryptographic strength means the cipher is very difficult to break.
