Let’s sum things up:
Network security is a set of technologies and procedures with the purpose of
protecting information systems in terms of confidentiality, integrity and
availability of information.
Why did I choose to say these 3 difficult to pronounce words?
Because those 3 fellas are the pillars of network security. If an enterprise isn’t
able to guarantee all three of these conditions It means that the enterprise has
been negligent in terms of cybersecurity, therefore you shall not trust it
because your sensitive information may end in real danger.
To evaluate security, it is usually necessary to identify the dangers,
vulnerabilities and risks that the information may face.
In particular cyber threats are usually divided into two main types: natural and
human.
Natural ones do not depend much on an efficient network security, but they are
out of our control events for example earthquakes, floods, wars, acts of
vandalism, anything that we can classify as a non-IT events.
Human menaces on the other hand are also called cyber-attacks. These attacks
are considered crimes and punished by the law.
The peculiar thing about it is that a cyber-attack has the purpose of stealing or
deleting someone else’s information.
There are many types of cyber-attacks, we’ll talk about some of the most
commons, threats that we could all happen to stumble into:
Phishing Attacks: Phishing is a type of attack where cybercriminals send
deceptive emails, messages that appear to come from a legitimate source to
trick individuals into revealing sensitive information, such as passwords, credit
card numbers, or any type of sensitive data.
Ransomware Attacks: Ransomware is a malicious software that encrypts files
on a victim's computer, keeping them inaccessible until a ransom is paid.
These attacks have become increasingly prevalent, with cybercriminals
demanding payments in cryptocurrency to unlock the encrypted files.
Malware Attacks: Malware refers to malicious software designed to gain
unauthorized access to or damage a computer system. This category includes
various types of infections viruses, worms and trojans horses. (Types of
infections are a subset of cyberattacks, but it doesn’t mean that they’re less
dangerous)
It's important to note that cyber threats evolve constantly, and new types of
attacks emerge as soon as technology advances.
