Cyber security is an approach and mindset for understanding and analyzing digital devices in a variety of ways, sometimes referred to as “out of the box.” In general, Cyber Security is a very broad topic since any equipment interacting via digital medium might be vulnerable and must be checked, i.e., from CPU registers to Data Centers, each layer and software must be evaluated independently to reduce the risk of security breach.
In the industry, cyber security is often classified into two categories.
1 – Offensive
2- Defensive
In Offensive Security analysts/engineers use hacker tactics to check for any loophole/vulnerability in the system and how to exploit it, as well as the risk level of vulnerability. On the other hand, in Defensive Security engineers harden system/network security so that it can detect at the initial stage and prevent attacker from making attack mature. There are millions of attack vectors only a few can exploit the vulnerability, but others might do significant harm to the system by putting it into panic state or preventing it from providing services to clients.
Penetration Testing to test the Boundaries of a Infrastructure
Penetration Testing is a way for confirming the existing condition of infrastructure is safe. It is best practice to assure security by testing infrastructure prior to a security incident. This is referred to as Penetration Testing. There are several approaches for doing a penetration test. The most famous are these three.
1- Black Box Penetration Testing
2- Grey Box Penetration Testing
3- White Box Penetration Testing
The goal of these several tests is to analyze and adjust the surface of attack from various points of view. Pentesters in White Box Penetration Testing have practically every privilege and knowledge of the network, as well as source code in some circumstances. Pentesters in Grey Box Penetration Testing have user or client level privileges and have little understanding of networks and their structures. In Black Box Penetration Testing, the Pentester has the least knowledge of everything, and the test is performed externally, which is why it is sometimes referred to as external penetration testing.
Ethical hacking is also referred to as the same terminology with a broader scope because it covers more than it. While a Bug Bounty with a certain scope is also referred to as the same.
Exploit Development for manipulation of system
Exploit Development is a strategy for manipulating a system or programme to fulfil a specific task. Exploits may be created for a variety of applications and services. In general, there are two sorts of exploits: local and remote. Local exploits are generally kernel level to exploit vulnerabilities that are used to escalate privileges once an attacker has gained access to the system. Any language, high or low level, can be used to write an exploit. Shellcode refers to code that executes directly into a programme or system (\x00\x42) Shellcode looks like this in system hex code: x00 represents terminate or null, and x42 means character B.
This domain is regarded as one of the most difficult in cyber security since candidates must comprehend a variety of concepts during the development and deployment of exploits. Let’s use an example to create a basic exploit.
1- Name of Operating System
a. Version
b. Build
c. Types (x86\x6_64)
2- Processer Type (In some cases):
a. Intel
b. AMD
3- Remote Applications
a. Over the network
b. Different segment
4- Programming Languages (Depends on Application and System)
a. Python
b. JavaScript
c. Assembly
d. C/C++
5- Debuggers (Depend Upon System)
a. Immunity
b. OllyDBG
c. WinDBG
d. IDA Pro
6- Exploit Mitigrations
a. SGX
b. TPM
c. CGF
d. kCFG
e. ACG
f. DEP
g. ASLR
h. SafeSEH
i. SEH
j. SEHOP
Before creating and deploying an exploit, the user must understand these concepts. Virtualization technology allows for practice in a virtual environment (VMware. Hyper-V, Virtual Box, etc.).
Bug Bounty for secure your public interface
Bug Bounty program is use to identify flaws and vulnerabilities into website/App. The candidates participate in such program known as bug hunters. The specifics of bug bounty program might differ from one business to the next. Some businesses may proclaim their apps “open season,” allowing cybersecurity professionals to evaluate for any conceivable weakness in the firm’s attack surface. Others may designate which applications and web pages are “in scope,” as well as specific vulnerabilities analysts can and will not analyze for.
The fundamental advantage of this program is that it allows a business to identify and patch a variety of weaknesses in their applications. If these flaws were identified and attacked by a black hat hacker before the company could address them, the consequences may be severe. A bug bounty programmer increases the likelihood of uncovering flaws before they are employed in attacks. This protects the company’s reputation and reduces the possibility of greater hacks. This Program also provide a business people with skills that would otherwise be difficult or even impossible to attract and maintain in-house.
Considering Cyber Security to be a strategy rather than a domain. Everything is connected to the others, and in the age of cyber devices and IoT, most devices work collaboratively with one another to help users through using their cyber space to protect that cyber space in which digital devices are connected to one another, Sectechs offers a variety of Cyber Security Training courses and services.
A white hat hacker is someone who utilizes their talents to find security bugs in devices, applications, or networks. White hat hackers, on the other hand, abide by the law when it comes to cybercrime, as opposed to black hat hackers. White hat hackers, also known as ethical hackers, solely look for bugs or exploitation when it is lawful to do so. They have computer experts those are especially trained for vulnerability management by applying their patches and covering loop holes
They are also computer specialists and security hackers. he may occasionally violate laws or conventional ethical norms, but they lack the cunning pretensions that characterise black hat hackers. When they find a vulnerability, they may offer to mould it for a modest price instead of informing the merchant how to exploit it.
