CYBER SECURITY

Common Network Analysis Tool For Cyber Security Analysts   A SOC relies on a supporting infrastructure of tools and systems that provide the following services: Network mapping Network monitoring Vulnerability detection Penetration testing Data collection Threat and anomaly detection Data aggregation and correlation   One tool that is used by […]

  In my previous article, I have talked about some of the facts that you need to know about computer security awareness. In this article, I want to look at seven major threats to system security. Follow me as we are going to look at that together in this article. Facts about System […]

  In my previous article, I have talked about all that you need to know about networks. In this article, I want to talk about some of the network basics that you need to know as a network security expert. Follow me as we are going to look at that […]

Statistical techniques can be used to evaluate the risk that exploits will be successful in a given network. This type of analysis can help decision-makers to better evaluate the cost of mitigating a threat with the damage that an exploit could cause. Two general approaches used to do this are […]

Worms share similar characteristics. They all exploit an enabling vulnerability, have a way to propagate themselves, and they all contain a payload. Worm Components Despite the mitigation techniques that have emerged over the years, worms have continued to evolve and pose a persistent threat. Worms have become more sophisticated over […]

  The term Trojan horse originated from Greek mythology. Greek warriors offered the people of Troy (the Trojans) a giant hollow horse as a gift. The Trojans brought the giant horse into their walled city, unaware that it contained many Greek warriors. At night, after most Trojans were asleep, the […]

  It has been mentioned on several occasions that blogging is part of online marketing. Essentially, it is a strategy that is closely linked to many other segments that together make what we know as online marketing, i.e., the promotion of a brand or business using online resources and media. […]

The security of the computer allows users to use the computer while keeping safe from threats.   Computer Security can also be defined as managing all components of computer systems that can provide secrecy, credibility, and availability. Data, software, firmware, and hardware are among these components.     Tip 1:  […]

  In my previous article, I talked about all that you need to know about networks. In this article, I want to talk about all that you need to know about Home Networks. Follow me as we are going to look at that together in this article.      What […]

  Before I start writing this article, here is a disclaimer. I am not writing this article to rubbish Nigeria as a country and I am not a Yahoo Boy and I will never in my wildest dream support their nefarious activities. I just wanted ordinary Nigerians and all my […]

Simply having a wired or wireless physical connection between end devices is not enough to enable communication. For communication to occur, devices must know “how” to communicate. Communication, whether face-to-face or over a network, is governed by rules called protocols. These protocols are specific to the type of communication method […]

Knowing the OSI reference model and the TCP/IP protocol model will come in handy when you learn about how data is encapsulated as it moves across a network. It is not as simple as a physical letter being sent through the mail system. In this article, I will be talking […]

In my previous article, I have talked much about how data travels across the network. In this article, I want to talk more about MAC addresses and IP Addresses. Follow me as we will look at that in this article. There are two primary addresses assigned to a device on […]

If your network is using the IPv4 communications protocol, the Address Resolution Protocol, or ARP, is what you need to map IPv4 addresses to MAC addresses. This topic explains how ARP works. Every IP device on an Ethernet network has a unique Ethernet MAC address. When a device sends an […]

Application layer programs generate data that must be exchanged between the source and destination hosts. The transport layer is responsible for logical communications between applications running on different hosts. This may include services such as establishing a temporary session between two hosts and the reliable transmission of information for an […]

You already know the fundamentals of TCP. Understanding the role of port numbers will help you to grasp the details of the TCP communication process. In this topic, you will also learn about the TCP three-way handshake and session termination processes. Each application process running on a server is configured […]

The Dynamic Host Configuration Protocol (DHCP) for IPv4 service automates the assignment of IPv4 addresses, subnet masks, gateways, and other IPv4 networking parameters. This is referred to as dynamic addressing. The alternative to dynamic addressing is static addressing. When using static addressing, the network administrator manually enters IP address information […]

The webservers that we so often connect to using names like www⋅cisco⋅com, are actually reached by assigning IP addresses to packets. On the internet, these domain names are much easier for people to remember than an IP address such as 74.163.4.161. If Cisco decides to change the numeric address of […]

  The network devices that people are most familiar with are end devices. To distinguish one end device from another, each end device on a network has an address. When an end device initiates communication, it uses the address of the destination end device to specify where to deliver the […]
