If you don’t already know what Pretty Good Privacy (PGP) is; you may have heard of PGP before, perhaps during a discussion on how to secure your communications, or perhaps in one of those how-to maintain privacy guides. PGP is a popular solution for encrypting, decrypting, signing, and verifying messages and files, often found in email communications and package repository identity verification (because security matters). Most generic guides simply explain PGP at a high-level or how to en

Introduction to TFTP The Trivial File Transfer Protocol (TFTP) is designed to provide a bare-bones method of sending data from a server to a client. Its main use is for firmware upgrades and similar... Go on to the site to read the full article

This weeks lab lead me to install Wireshark on my home network to check out the activity. Because of this, I wanted more information about what I saw and stumbled across securityboulevard.com. There were a lot of blog entries on Wireshark. As an example of one of the many blogs on this site containing Wireshark, check out the blog about network Traffic Analysis for IR:TFTP with Wireshark. This site is a good place to learn more about the tool.

Microsoft Baseline Security Analyzer is extremely limited, and will only assess the status of Microsoft software. We review 6 best alternative vulnerability scanners.

After performing the lab this week I thought it would be a great idea to install and get some practice with Microsoft Baseline Security Analyzer for Windows 10. I found it is no longer supported and not available for download on Microsoft website. Here is a link discussing 6 alternatives.

It is very well known that Active Directory credentials can be compromised quite easily. It is therefore vital for companies to better secure those credentials in order to avoid a network breach. Active Directory – One Identity Source for all Access Today, 90% of companies still rely on Active Directory as the primary source of …

Businesses use information technology to quickly and effectively process information. Employees use electronic mail and Voice Over Internet Protocol (VOIP) telephone systems to communicate. Electronic data interchange (EDI) is used to transmit data including orders and payments from one company to another. Servers process information and store large amounts of data. Desktop computers, laptops and wireless devices are used by employees to create, process, manage and communicate information. What do you when your information technology stops working?

Here is a link to the Department of Homeland Security’s IT disaster Recovery Plan. If you read the content you will see that it lines up well with the information provided in this week’s reading. The article speaks to DRP, BIA and BCP this shows how relevant the material we are learning is in today’s world of cyber security.

Every year, we take time to recognize our Most Valuable Security Researchers (MVRs) based on the volume, accuracy and impact of their vulnerability reports.

This weeks activity made me aware of the Microsoft Security Response Center. I found they also have a blog and this link is to a bit about the 2020′s Most Valuable Security Researchers. I found it interesting what the future may hold for some. The blog also has additional links, one is to the MSRC Researchers Recognition Program and provides details about how it works.

Keeping in line with this weeks assignment of creating a report for “Internal Use Only” data classification standards, I found this link that discusses vulnerabilities of what i feel is the most impacted domain, the user domain.

Welcome back, my novice hackers! Reconnaissance is one of the most important preparatory steps to hacking. As I have emphasized many times before here on Null Byte, you must know the operating system, the ports, the services, the applications, and sometimes even the language of the target to be effective. If you haven't taken the time to gather this info, then you are likely wasting your time.

Check out this site that discusses Nmap use in active reconnaissance. I found this site while looking for additional learning on Zenmap which is a tool we used in this weeks lab. I am assuming this site is to learn about hacking to prevent hacking.

Popular Mintegral iOS software development kit (SDK) used by over 1,200 apps contains malicious code with the goal of perpetrating mobile ad-click fraud and capturing sensitive information.

I found this particular article interesting due to the fact that many times the threat is not readily apparent. This is not a vulnerability in the SDK that leaves it open to attack, this is the SDK itself that is the perpetrator.
