What is a Honeypot?
How do they enhance your cybersecurity?
A honeypot is a decoy system designed to attract and analyze cyber-attacks. It serves as a manufactured target that lures cybercriminals away from legitimate systems, allowing security teams to gather intelligence about the attackers' methods and motivations. A good honeypot will allow you to understand what sort of cyber attacks your production machines may face.
What is ZTA?
How can you buils a Zero Trust Architecture?
ZTA is a security framework that continuously verifies all users and devices before granting access to resources, regardless of their location or network. You should use Zero Trust to gain visibility and context for all your traffic – across user, device, location and application – plus zoning capabilities for visibility into internal traffic.
What Is IPSec?
How does IPSec work and provide data security?
IPSec is a suite of protocols between two communication points across the IP network that provide data authentication, integrity, and confidentiality... When properly configured, an IPSEC VPN provides multiple layers of security that ensure the security mode and integrity of the data that is being transmitted through the encrypted tunnel.
What is Elasticsearch Stack? How does Elasticsearch work?
Elasticsearch is the central component of the Elastic Stack, a set of open-source tools for data ingestion, enrichment, storage, analysis, and visualization. “ELK” stack after its components Elasticsearch, Logstash, and Kibana and now also includes Beats. It can provide you actionable insights from any structured or unstructured data...
What Exactly is Shadow IT? How can you deal efficiently with it?
The security aspects associated with Shadow IT are real and must not be overlooked but they can only be understood when put in the right perspective. It doesn’t make sense to assume upfront that any Shadow IT solution introduces risk and is therefore a hazard that must be avoided.
Information Security Vs. Cybersecurity: What is the difference?
Many years ago, the term 'Information Security' was very popular for businesses. In recent years, it is the term 'Cybersecurity' which had gained a lot of momentum. Not only it has got more attention, it has attracted a lot of research too. They are related processes, but both terms don't mean the same. !
What is DNS Poisoning? How do attackers poison DNS caches?
DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, e.g. an IP address, to the clients. It can attack through MITM, DNS Server Hijack, or spamming!
What is Reverse Proxy? How is it different from Forward Proxy?
A reverse proxy appears to any client to be an ordinary web server, but in reality merely acts as an intermediary that forwards the client's requests to one or more ordinary web servers. It provides an additional level of abstraction and control to ensure the smooth flow of network traffic between clients and your servers.
What is a SD-WAN? How does a SD-WAN work?
A software-defined wide area network (SD-WAN) is a virtualized service that connects and extends enterprise networks over large geographical distances. SD-WAN does not need to engage with physical routers directly. It leverages any combination of transport services (MPLS, LTE, broadband internet) to securely connect users to applications.
What is the difference between IT and OT? Why is OT Security very important?
For IT security, computers and software are required in business operations to collect, store, process, and share data securely. On the other hand, with OT hardware and software, factories and power plants can ensure safety and boost efficiency in their operations.
What is a Port Scan? What are major port scanning techniques?
A port scan is one of the fundamental technique that is used to identify the open doors or weak-points in a network. It involves sending packets to specific ports and analyzing the responses to determine which ports are open and available for communication.
What is UEFI Secure Boot? Beware of TRICKBOOT!
Secure Boot is a UEFI firmware security feature that ensures only immutable and signed software are loaded during the boot time. Secure Boot leverages digital signatures to validate the authenticity, source, and integrity of the code that is loaded. It ensures that only trusted software is executed during the boot process.
TECHNOLOGY EXPLAINED: How do Firewalls work?
You can think of a firewall like a security guard standing at the door, checking the ID of everythng that tries to enter or exit the network. Firewalls filter network traffic so that you only receive data that you should be getting. No firewall works perfectly, and a lot of a firewall's effectiveness depends on how you configure it.
What is LDAP? What can you do to Enhance LDAP Security?
Don't be confused with Active Directory, which is that directory server that makes use of the LDAP protocol. Although Active Directory is the industry standard directory service, you may hear people say that they ‘use LDAP’ instead. LDAP is a central place to store usernames and passwords, allowing different applications, services to validate users.
How does Intrusion Detection System actually work?
An IDS operates by examining network traffic and identifying potential threats based on predefined security policies or known attack signatures. You can implement an IDS protection as a software application that runs on your customer hardware or it can be run as a network security appliance OR cloud-based solution....
Evil-Twin Attacks: How can you avoid them?
Cyber criminal uses a computer or other device to create, in a public place such as a train station, airport or hotel, a WiFi network with the same name as the existing public network with some small variation, waits for someone to sign up, and then captures their data when they connect to their email or other services.
Buffer Overflow Attacks: These are the root reasons…
An attacker can deliberately feed a carefully crafted input into a program that will cause the program to try and store that input in a buffer that isn’t large enough, overwriting portions of memory connected to the buffer space. This can lead to data corruption, program crashes, or even the execution of malicious code.
DDoS Attacks: How can you mitigate a DDoS Attack?
A DoS Attack (Denial Of Service) is basically a malicious attempted made by threat-actors to attack the 'Availability' of a targeted system, a website or a web-based application, to its legitimate end-users. Hackers typically generate a large volume of requests to overwhelm the targeted system.
