Developers with cyber Security skills are the biggest IT heroes these days. Small to large enterprises are the victims of cyber breach. Hackers are getting very active over the past few years. Therefore, organizations hunt for experts to prevent bugs and secure their systems.
Expertise in Computing Resources :
Computer security is one of the primary concerns of the companies. To become a full proof skilled person in security, you must have knowledge of common languages used in developing computer applications and other resources like c++, c, python, etc.
Having good knowledge about Network system distribution and hardware resources that are being used, will help you to upgrade your understanding of the web.
Practical knowledge of algorithms and techniques used in operating systems like Linux, Windows, Macintosh is necessary because most of the people use these operating systems.
Existing Systems & Technologies :
The best technique to understand security is to learn existing systems and technologies that are being used for the purpose of security.
Cryptography is the technique for providing secure communication over network channel and improving data integrity, confidentiality and authentication. The modern approaches used in cryptography are :
1). Symmetric Key Cryptography: In the symmetric key crypto approach, a single key is used for accessing the data from both the sender and receiver side. The block or stream cipher method is used to encrypt data over the network.
2). Public Key Cryptography: In the public key crypto methodology, the public key is distributed and the private key is kept safe. The use of the public key is for encryption but in order to decrypt the data, you need the private key.
3). Cryptanalysis: The main concept of cryptanalysis is to find a bug in crypto methods. The approach is used for analyzing a variety of attacks while finding solution method for prevention.
Learning from Public Resources :
Resources on the internet like Cyber Security blogs, posts on social media platform, including Facebook, Twitter, Pinterest, news platforms, articles, video tutorials, ebooks, pdf, and cyber security training, can be helpful for updating your security knowledge base. They will be able to improve your understanding of how and where the latest breach occurred and how it is executed.
There are a number of open source and paid tools available in the market for spying on a network and detecting cyber breaches. Getting practical knowledge of this software will help you build a secure career in the future. Some of these tools are:
Kali Linux: It is a linus distributed tool for penetration testing against cyber attack management. Anyone can natively execute it on a computer’s hard disk.
NMAP: NMAP stands for network mapper. It is used to map a network and port. It scans for security and discovers host over a computer network.
Security Onion: It is a powerful tool which takes care of intrusion detection, monitoring, and managing log.
OpenSSH: It is a tool developed for remote login over secure shell layer. It encrypts network traffic during connectivity and data transfer, eliminating the risk of hijacking or another intrusion over the network.
Wireshark: Wireshark is an open-source packet analyzer for analyzing and controlling traffic networking layers.
Snort: Snort is an open source Intrusion detection system for preventing network intrusion or malware attacks. It halts and analyses cyber threats.
Google Rapid Response: This tool is a python based client agent which is installed on the client side. It supports targeted systems remotely with communication on the python based infrastructure.
Understanding the types of security attacks used by hackers will be very beneficial to you. The types of attacks are:
Denial of Service(DoS) attack by flooding traffic on the host server
Spoofing via email, IP address or biometric as an act of masquerading valid entity to get access to the system.
Phishing Attacks attempt to acquire useful details like username, card information etc
SQL Injections by sending binary input cases for breaking in the system.
Cross Site Scripting is the method of sending malicious code in the form of script.
Malware attacks like ransomware
So acquiring detailed knowledge of such attacks will allow you to stand in the front of cyber security experts. A journey that starts from the beginning phase of data collection to figuring out the algorithm technique to break in will make your skills stronger.
