Common Software Security Key Questions and Answers

When it comes to software, each license will have it’s own security key which is for each individual user or registered version of the software. With so much software out there in the world today, there can be a lot of questions and researched queries in reference to how to find or locate such keys and codes that you once had.

To help with this process, we’ve highlighted some of the most common software security key questions and answers for you below.

Software Security Key Q&A 101

Define Cryptography. 

Cryptography can be defined as the practice and study of the techniques used for securing information and communication to protect the data from people who the data is not intended for.

Explain the difference between IDS and IPS. 

IDS stands for Intrusion Detection System. The system is designed only to detect any form of intrusion, and then the administrator takes care of intrusion. IPS stands for Intrusion Prevention System. The system is designed to detect and also take action to prevent intrusion. 

What is the difference between encryption and hashing?

Encryption and hashing are used to convert readable data into an unreadable format. But the difference is that encrypted data can be converted back into a readable format by decryption, while hashed data cannot be converted back to its readable format. 

What response codes can be received from a web application, and what do they stand for? 

1xx – Informational responses

2xx – Success

3xx – Redirection

4xx – Client-side error

5xx – Server-side error

What steps will you take to secure a server?

Secure servers use the SSL (Secure Sockets Layer) protocol for data encryption and decryption to protect data from unauthorized use.

Here are four steps to secure a server:

Step 1

Ensure that you have a secure password for your root users and administrators 

Step 2

Make new users on your system. These users will be the ones to manage the system. 

Step 3

Remove remote access from the default root/administrator accounts

Step 4

Configure your firewall rules for remote access

What is Vulnerability?

Vulnerability is a loophole or weakness within a system through which intruders or bugs can attack the system. If security testing is not carried out on the system, the chances of vulnerabilities are high. Patches and fixes are required from time to time to secure the system from vulnerabilities.

What is a Firewall?

A firewall is a security system designed for the network. It is usually set on the boundaries of any system or network that monitors or controls network traffic. Firewalls are used to protect your system from malware, worms, and viruses. It can also prevent content filtering and remote access. 

What is a brute force attack? How to prevent it?

A brute force attack is a method used by hackers to try out different combinations of pins and passwords to access your system. Most times, brute force attacks are automated, where the software tries different combinations to login with your credentials. 

You can prevent Brute Force Attacks in the following ways:

  • Setting password length
  • Increase password complexity
  • Set limit on login failures

Differentiate between SSL and TLS. 

The difference between SSL and TLS is that SSL works to verify the identity of the person you are communicating with, while TLS offers a secure channel between two clients.

What is WAF? 

WAF is an acronym of Web Application Firewall. It is used to protect the software by filtering and monitoring incoming and outgoing traffic between the software and the internet. 

What is TCP Three-way handshake? 

A TCP Three-way handshake is used in a network to make a connection between a local server and localhost. It usually requires the client and server to negotiate synchronization and acknowledgment packets before starting communication.

How can you protect email messages?

Cipher algorithm can be used to protect your email, credit card information, and corporate data. 

What are the risks associated with public Wi-Fi?

The risks associated with public Wi-Fi include karma, sniffing, war-driving, brute force attack, etc. A public Wi-Fi may identify data that is passed through a network device like emails, browsing history, passwords, and credit card details

What are the steps to secure a web server?

  • Update ownership of the file.
  • Keep your webserver updated.
  • Disable extra modules in the webserver.
  • Delete default scripts.

What is WEP cracking?

WEP cracking is a method that is used for a security breach in wireless networks. The two types of WEP cracking include Active cracking and Passive cracking.

What is security auditing?

Security auditing is the internal inspection of applications and operating systems for any security flaws. A security audit can also be done by inspecting the code line by line. 

What is Security Scanning? 

Security scanning has to do with identifying network and system risks and providing solutions for tackling the risks. Security scanning can be done manually and automatically. 

What is Security Testing?

Security Testing is a type of software testing that ensures that software systems and apps are free from threats and vulnerabilities, resulting in any form of loss. 

What is ISO/IEC 17799?

ISO/IEC 17799 is the international standard code and best practices for Information Security Management. It contains the guidelines for all organizations, small or big, for Information security.

What is a honeypot?

A honeypot is a fake computer system created to act like a real system to attract hackers to attack the system. Honeypots are designed to find out if there are any loopholes in the system and to provide solutions for such attacks.

Define 2FA. And how can it be implemented for public websites?

2FA is simply an extra layer of protection known as. 2FA requires more than a password and username to allow access. It also requires information that only the user has to instantly access, such as a token sent to a registered phone number or email address.
