Lorenzo Biasiolo 3°AI INFORMATION SECURITY

What does computer security mean? The term computer security means that computer science branch that deals with the analysis of threats, vulnerabilities and risks associated with information assets to protect them from possible attacks that could cause damage.

What do they offer to customers? Cyber asset protection is achieved through technical and organizational measures to ensure: integrity property confidentiality properties availability of properties

How important has security become? The interest in the security of computer systems has grown in recent years, proportionally with their spread and their role in society. Many ex-crackers are computer security company executives today.

How to have a secure system The computer system must be able to prevent the direct or indirect alteration of information, either by unauthorized individuals, or due to accidents.

Attacks by unauthorized users The cyber attack protection is obtained by acting on several levels: the first at the physical level the second at the logical level

Accidental events To prevent accidental events, there are no general solutions, but a first remedy is doing a regular backup of your system.

Data availability Achieving availability depends on several factors that interfere between user and system, such as: basic software robustness, reliability of equipment and the environments in which they are placed.

Most common hazards These are some of the most famous types of dangers in computer science:

Phishing Phishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details directly from users. Phishing is typically carried out by email trap or instant messaging, and it often directs users to enter details at a fake website whose looks are almost identical to the legitimate one.

Backdoor A backdoor in a computer system is a cryptosystem or an algorithm, or any secret method of bypassing normal authentication or security controls. They may exist for a different number of reason. They may have been added by an authorized subject to allow a legitimate access or by an attacker for malicious reasons.
