Problems Related with Computer Security (CSS)

Too be continued......... 

Problems related with Computer Security are :

1. Phishing
2. Vishing
3. Smishing

4. Pharming

5. Vulnerability
6. Exposures

1. Phishing

Phishing is an attempt to obtain users sensitives information, including credit card details and banking information, by disguising as a trustworthy entity in an online communication (e-mail, social media, etc.)

2. Vishing 

Vishing (Voice Phishing) is an attempt of fraudsters to persuade the victim to deliver personal information or transfer money over the phone.

3. Smishing :

Smishing (SMS Phishing) is any case where sent text messages attempt to make potential victims pay more or click on suspicious links.

4. Pharming :

i) Pharming is a cyber attack meant to redirect a website's traffic to another, fake one.
ii) Pharming can be done either by changing the hosts files on a victim's machine or by exploiting a flaw in DNS server software.
iii) In Phashing, no conscious user interaction is required.

5. Vulnerability :

i) Vulnerability is a software mistake that enables a bad actor to attack a system or network by directly accessing it.
ii) Vulnerability can permit an attacker to act as a super - user or even a system admin  and granting them full access privileges.

6. Exposures :

i) It provides a malicious actor with indirect access to a system or a network.

ii) An exposure could enable a hacker to harvest sensitive information in a secret manner.

Security Measures :

To protect the system, security measures can be taken at the following levels ;

1. Physical

2. Human

3. Operating System

4. Networking System 

1. Physical

i).  The sites containing computer system must be physically secured against armed and malicious intruders.

ii). The workstations must be carefully  protected.

2. Human

i). Only appropriate users must have the authorization to access the system.

ii). Phishing (collecting confidential information) and dumpster diving (collecting basic information so as to gain unauthorized access) must be avoided.

3. Operating System

The system must protect itself from accidental or purposeful security breaches.

4. Networking System 

i).  Almost all of the information is shared b/w different system via a network.

ii). Intercepting these data could be just as harmful as breaking into a computer.

iii). Henceforth, Network Should be properly secured against such attacks.

Protect Computer System Hardware :

Five steps to protect computer system hardware :-
1. Install Firewall
2. Install Anti-virus software
3. Install Anti-spyware software
4. Use complex and secure passwords
5. check on the security setting of the browser

1. Install Firewall

i).  A firewall enacts the role of a security guard.

ii). A firewall is the step to provide security and any unauthorized program trying to come in through the internet.

2. Install Anti-virus Software 

i) Anti-Virus is a software that helps to protect the computer from any unauthorized code or software that creates a threat to the system.

ii). Unauthorized software includes viruses, keyloggers, Trojans etc.

iii). This might slow down the processing speed of our computer, delete important files access personal information.

3. Install Anti-Spyware software 

i). Spyware is a software program that collects personal information or information about an organization without their approval.

ii). This information is redirected to a third party website.

iii). Anti-spyware software is solely dedicated to combat spyware.

iv). Anti-spyware software offers real time protection.

v). It scans all the incoming information and helps in blocking the thereat once detected.

4. Use complex and secure passwords 

i). For maintaining system we have to use strong and complex passwords.

ii). Complex passwords are difficult for the hackers to find.

5. Check on the security setting of the browser

i). Browsers have various security and privacy setting that we should review and set to be level desire.

ii). Recent browsers give us ability to tell websites to not track our movements, increasing our privacy and security.
