We have been talking about data vulnerability for quite some time now. Isn’t that right?
And you already know about the solution to it already as well. Of course, it’s focusing on Cyber Security of your organization.
We cannot emphasize more on this fact that in the era that runs on continuous delivery, cybersecurity is the only key to be secured by protecting your data.
Data manipulation is a serious issue that can clear up millions from any organization’s bank account. So, unless the cybersecurity system of an organization is extremely strong, the risk of getting data robbed will always be there.
And what’s the easiest way to build a strong cybersecurity system?
Hiring cybersecurity professionals.
And how can you get hired as one? With a thorough preparation of course.
So here comes the top 20 cybersecurity questions to look up to right before you are going to sit for your cybersecurity examination!
Cryptography is the practice and study of techniques to secure information and communication that is mainly used to protect the data from any third party intruders who don’t have access to that data
IDS is an Intrusion Detection System that only detects intrusions and the administrator takes care of preventing the intrusion. On the other hand, in IPS (Intrusion Prevention System) the system detects the intrusion as well as taking actions to prevent the intrusion.
CIA is basically the initials for Confidentiality, Integrity, and Availability. It is basically a model designed to guide policies for Information Security. Let’s see what are the meaning of these three components:
The information should be accessible and readable only to people who are authorized to it and should be strongly encrypted just against hacking or data manipulation.
Integrity makes sure that the data is not corrupted, tampered, or modified by unauthorized people.
The data should be available to the user as per their requirement with an assurance of maintenance of Hardware, upgradation, Data Backups and Recovery, management of Network Bottlenecks.
Although Encryption and Hashing both can be used to convert readable data into an unreadable format, encrypted data can be converted back to original data with the help of decryption but the hashed data can’t be converted back to original data.
A Firewall is a network security system set on the boundaries of the system or network that monitors and controls the network traffic. We use firewalls to protect the system/network from viruses, worms, and malware. It can also be used to prevent remote access and content filtering.
Vulnerability Assessment is the process by which we can find flaws on the target while the organization is aware of the system’s flaws and looking forward to find these flaws and prioritize them for fixing.
Penetration Testing is the process through which we can find vulnerabilities on the target. This helps the organization in exploring the ways of hacking their system/network.
A three-way handshake is a method that is used in a TCP/IP network. It creates a connection between a host and a client. For being a three-step method, it is called a three-way handshake. The three steps where the client and the server exchange packets are as follows:
The response codes that can be received from a Web Application are as follows:
1xx – Informational responses
2xx – Success
3xx – Redirection
4xx – Client-side error
5xx – Server-side error
Traceroute is a tool to determine the path of a packet by listing all the points (mainly routers) the packet passes through. This becomes helpful when the packet is not reaching its destination. Traceroute checks out the exact point where the connection stopped or broke to identify the point of failure.
HIDS or Host IDS and NIDS or Network IDS are both Intrusion Detection System that works towards detecting the intrusions. Although, HIDS is set up on a particular host or device and monitors the traffic of that particular device along with suspicious system activities. Whereas, NIDS is set up on a network to monitors the traffic of all devices of the network.
You need to go through the following steps to set up a firewall:
SSL(Secure Sockets Layer) is an industry-standard security technology that creates encrypted connections between Web Server and a Browser. It is used to maintain data privacy as well as protecting the information of online transactions. You need to follow the steps mentioned below to establish an SSL
Secure servers use the Secure Sockets Layer (SSL) protocol for data encryption and decryption to protect data from unauthorized interception.
Here are four simple ways to secure server:
Step 1: Make sure you have a secure password for your root and administrator users
Step 2: The next thing you need to do is make new users on your system. These will be the users you use to manage the system
Step 3: Remove remote access from the default root/administrator accounts
Step 4: The next step is to configure your firewall rules for remote access
Data Leakage is an intentional or unintentional transmission of data from the organization to some external unauthorized destination. It is mainly the revelation of confidential information to an unauthorized party. Data Leakage can be divided into 3 categories based on how it happens:
Data Leakage can be prevented by using tools, software, and strategies known as DLP(Data Leakage Prevention) Tools.
Brute Force is a way of finding out the right credentials by repetitively trying all the permutations and combinations of possible credentials. In most cases, brute force attacks are automated where the tool/software automatically tries to login with a list of credentials. There are various ways to prevent Brute Force attacks. Some of them are:
Port Scanning is the technique used to identify open ports and service available on a host. Hackers use port scanning to find information that can be helpful to exploit vulnerabilities. Administrators use Port Scanning to verify the security policies of the network. Some of the common Port Scanning Techniques are:
An OSI model is a reference model for how applications communicate over a network. The purpose of an OSI reference is to guide vendors and developers so the digital communication products and software programs can interoperate.
Following are the OSI layers:
VPN stands for Virtual Private Network. It is used to create a safe and encrypted connection. When you use a VPN, the data from the client is sent to a point in the VPN where it is encrypted and then sent through the internet to another point. At this point, the data is decrypted and sent to the server. When the server sends a response, the response is sent to a point in the VPN where it is encrypted and this encrypted data is sent to another point in the VPN where it is decrypted. And finally, the decrypted data is sent to the client. The whole point of using a VPN is to ensure encrypted data transfer.
