Network Security

 

 

We use computer systems everyday, and whether we intentionally go into websites to

browse or go on social medias or not, without us knowing, many apps and devices like TVs,

tablets, mobiel phones exchange information. As a lot of data can be exchanged online and can

also be exposed, and as there are always security holes that come up, one needs to always make

sure the os is up to date. The computer systems can be vulnerable to hacking or robbery(with

leaked location information), and more so.

 

There are a lot of security threats of computer systems, for instances, viruses and malware, data 

breaches, internet scams and spams.

For each threat, malware’s symptom would be showing slow system performance as

stealing information is happening and even rendering the system unusable. Phishing can lead to

unathorized transactions , usually wire transfers and P2P transfers (That are hard to recover),

identity theft(also that lead to financial damage), it often relies on social engineering to

manipulate users to give them out their confidential personal information. According to Kyi,

Stobert(2022), “The attacker has to decide how they want to carry out their attack. It may be a

physical social engineering attack (e.g., baiting targets with USB keys), or they may reach their

victims remotely. Email is very popular , but attacks may also be conducted using

SMS, social media, websites, QR codes, advertisements, and pop­ups.”

 

To protect one’s computer systems from these kinds of breaches, one needs to make sure

to have the operating system up­to­date, so that the security holes are all blocked up. Also one

needs to make sure to update their passwords every now and the, so that the log in information is

protected and not predicted. For preventing the damage from phishing, Desolda, G., Ferro, L. S.,

Marrella, A., Catarci, T., & Costabile, M. F(2022) said in their article, that the training system 

can help lowering the percentage of the victim rate.
