Network and Systems Hardening

Network hardening

Make sure your firewall is correctly configured, that all rules are periodically reviewed, that remote access points and users are secure, that any open network ports are blocked, that extraneous protocols and services are disabled and removed, that access lists are in place, and that network data is encrypted.

Systems Hardening

Audit your current systems: Conduct a thorough audit of your current technologies (you can use). To identify system weaknesses and order remedies, use security auditing techniques like configuration management, vulnerability scanning, and penetration testing. Utilize industry standards from NIST, Microsoft, CIS, DISA, and other sources to conduct system hardening assessments against resources.

Create a strategy for systems hardening: Not every system needs to be hardened at once. Instead, develop a strategy and plan based on the risks found in your IT ecosystem, and then utilize a staged approach to fix the most serious issues.

Patch vulnerabilities immediately: Make sure your mechanism for automating vulnerability identification and patching is in place. Determine vulnerabilities systematically, then give priority to fixing them. Vulnerabilities are sometimes impossible to patch. Make sure that alternative mitigations are in place in these situations, such as disabling admin rights—which many attacks require in order to exploit a vulnerability—and/or having cyber insurance in place.

Network hardening: Make sure your firewall is correctly configured, that all rules are periodically reviewed, that remote access points and users are secure, that any open network ports are blocked, that extraneous protocols and services are disabled and removed, that access lists are in place, and that network data is encrypted.

Server hardening: Place all company-hosted servers in a secure datacenter; avoid testing server hardening on live systems; harden servers before connecting them to the internet or other networks; avoid installing pointless software on servers; appropriately segregate servers; ensure that superuser and administrative shares are set up; and ensure that rights and access are limited in accordance with the principle of least privilege. Reduced port exposure is especially crucial in cloud environments to prevent infrastructure backdoor access or accidental data leaks.

Endpoint hardening: On every Mac and Windows endpoint, disable local admin rights. Make that there are no default passwords on workstations, laptops, or IoT. Block any superfluous communications and remove any unnecessary applications.

Application hardening: Remove any components or features you do not require, limit application access based on user roles and context, remove all sample files, and change any default passwords. In order to enforce password best practices' (password rotation, length, etc.), application passwords should therefore be controlled using a solution for application password management or privileged password management. Inspecting integrations with other apps and systems and eliminating or lowering unused integration components and rights should also be part of the hardening of applications.

Database hardening: Turn on node checking to confirm applications and users; set up admin limitations on what users can do in a database, such as by managing privileged access; database information should be encrypted both in transit and at rest; enforce strong passwords; add privileges for role-based access control (RBAC); eliminate inactive accounts;

Operating system hardening: Apply OS patches, service packs, and updates automatically; eliminate unused libraries, software, services, and functionality; and remove superfluous drivers. lock down local storage; increase privileged user controls, tighten registry and other system permissions, and log all activities, faults, and warnings.

Eliminate unnecessary accounts and privileges: Enforce least privilege by removing unnecessary accounts (such as orphaned accounts and unused accounts) and privileges throughout your IT infrastructure. This is one of the most powerful security practices for reducing the attack surface.

Concepts, Types, and Phases of Hacking

 Concepts, Types, and Phases of Hacking A hacker is someone who is intelligent enough to use various tools and techniques to gain unauthorized access to a system in order to steal information such as usernames, passwords, financial information, credit card information, business data, and personal information. Hackers are very skilled, capable of creating software, and exploring both hardware and software. Their motives can range from paying people to hack computers to engaging in unlawful activity for enjoyment. Black Hats Hacker with amazing talents who engages in malicious and destructive acts, often known as crackers White hats Security Analyst or individuals with hacking skills using them for defensive purpose  Gray Hats Gray Hats are those work for both offensively and defensively Suicide hackers Suicide hackers are those who aim for destruction without worrying about punishment. Script Kiddies Unskilled hackers, hacking and compromising systems using tools are scrip...

Vulnerability scanning application

 Nessus is an open-source network vulnerability scanner that uses the Common Vulnerabilities and Exposures architecture for easy cross-linking between compliant security tools. Nessus employs the Nessus Attack Scripting Language (NASL), a simple language that describes individual threats and potential attacks. Retina's function is to scan all the hosts on a network and report on any vulnerabilities found. It was written by eEye, who are well known for their security research.  SAINT is a commercial vulnerability assessment and penetration system. It was originally developed in the late 1990's as free UNIX tool based on the open source SATAN scanner. Later it went commercial and broadened into a whole suite of tools for vulnerability detection, exploitation, and asset management. It is available on multiple platforms, including appliances (SAINTbox) and cloud-hosted (SAINTcloud). Whisker is a C# tool for taking over Active Directory user and computer accounts by manipulating...

Steganography

The practice of steganography involves concealing a hidden message within an ordinary communication. This method is used to send a secret message to another person; nobody else in the path of the transmission will be aware of the secret message you intended to send. In real-world communications, this technique of obscuring secret signals has been employed for years. It has been utilized in digital communications ever since the development of digital communication.  There are numerous software tools for steganography. This software can hide your secret message using an image file, HTML file, DOC file, or any other kind of file. Steganography Tools 1.Whitespace Steganography 2.Image Steganography 3.Image Steganography 4.Document Steganography 5.Video Steganography 6.Audio Steganography 7.Folder Steganography 8.Spam/Email Steganography 9.Snow Tool 10.Open stego 11.Quick steo OpenStego Data can hide with password protection , it can extract when need.

Rootkits

 Rootkits A rootkit is a collection of software designed to provide privileged access to a remote user over the target system. Mostly, Rootkits are the collection of malicious software deployed after an attack, when the attacker has the  administrative access to the target system to maintain its privileged access for future. It creates a backdoor for an attacker; Rootkits often mask the existence of its software which helps to avoid detection. Types of Rootkits 1.Application Level Rootkits 2.Application Level Rootkits perform manipulation of standard 3.application files, modification of the behavior of the current application with an injection of codes. Kernel-Level Rootkits The kernel is the core of an OS. Kernel-Level Rootkits add additional codes (malicious), replace the section of codes of original Operating system kernel. Hardware / Firmware Level Rootkits Type of Rootkits that hides in hardware such as hard drive, network interface card, system BIOS, wh...
