Understanding the Different Types of Certificate Authorities 

/in


Establishing trust online is a crucial component of collaboration in the digital age. From using a third-party vendor to shopping online to communicating via email, companies and individuals rely on this trust to do business. How can they know they are communicating with the right person and not an actor behind a phishing scheme?

A certificate authority (CA) plays a vital role in making this happen. CAs follow strict industry standards, verify identities, and issue digital certificates. Here is your guide to what a CA is, why it matters, and the different types of CAs available today.

What Is a Certificate Authority (CA)?

Certificates ensure a system is who they say they are, but the system must also be assured that the certificate itself is genuine. This is where trusted third parties come into play. Certificate authorities are independent bodies that issue and vouch for certificates.

As a vital component of the public key infrastructure (PKI), CAs create digital certificates that cryptographically link public keys with the owners’ identities. The CA is responsible for validating the identity of the entity associated with a given public key and issuing the digital certificates that attest to this identity. The CA follows specific protocols to verify the requester’s identity before issuing the certificate. This protocol involves checking official documentation or performing a background check.

CAs also have mechanisms for revoking certificates. Revocation happens when a key associated with a certificate is compromised or if the entity that was issued a certificate no longer exists.

Importance of Certificate Authorities

CAs play a crucial role in ensuring internet security. Certificates can secure digital signatures and establish secure network connections via protocols such as HTTPS. 

Here are some of the top reasons why CAs are critical in the digital world:

  • Establishing trust. CAs provide the foundation of trust on the internet. For example, when users connect to a website, their browser trusts the website if it has a valid certificate issued by a trusted CA. Without this mechanism, it’s hard to establish trust between two parties that have never interacted….

Microsoft hack exposing government emails could have accessed other types of files: researchers

/in


The suspected Chinese-backed hack of U.S. government emails on Microsoft servers could be more damaging than previously thought, cybersecurity researchers said.

Microsoft announced this month that Chinese-backed hackers had accessed the email accounts of multiple government employees, putting information at risk. The U.S. government said that no classified information was disclosed in the cyberattack.

However, researchers at the cloud security firm Wiz claim that the method the hackers used to access emails — forged encryption keys — may also be used to access Microsoft Teams information, OneDrive files and other apps that have Microsoft logins.

“Identity provider’s signing keys are probably the most powerful secrets in the modern world,” Wiz Head of Research Shir Tamari said.

“With identity provider keys, one can gain immediate single hop access to everything, any email box, file service or cloud account.”

The researchers used internet archives to determine that the key used by the hackers was one of a small group of public keys used to verify logins, meaning that the hackers could effectively use the forged key to login to any account they wanted.

“The full impact of this incident is much larger than we initially understood it to be. We believe this event will have long lasting implications on our trust of the cloud and the core components that support it, above all, the identity layer which is the basic fabric of everything we do in cloud.” Tamari said. 

“At this stage, it is hard to determine the full extent of the incident as there were millions of applications that were potentially vulnerable, both Microsoft apps and customer apps, and the majority of them lack the sufficient logs to determine if they were compromised or not,” he added.

The compromised public key has since been removed, meaning accounts are no longer vulnerable.

Microsoft downplayed the possibility of the attack going beyond emails.

8 Types of Cyber Attacks You Should Know About

Types of Cyber Attacks

In today’s interconnected world, the importance of cybersecurity cannot be overstated. With advancements in technology come new vulnerabilities, and it’s crucial to stay informed about the types of cyber attacks that can threaten your digital safety. In this blog post, we will discuss eight common cyber attacks and provide tips on how to protect yourself and your business from these threats. By understanding these attack types and implementing proper security measures, you can take significant steps toward safeguarding your valuable data and personal information.

Phishing Attacks

One of the most popular and possibly disastrous types of cybercrime is the phishing assault. Cybercriminals employ social engineering to deceive their targets into giving up sensitive information or downloading malicious software. These assaults typically use email, SMS, and social media messages that appear to come from trusted sources such as banks, government agencies, or even friends.

Don’t fall for phishing by responding to suspicious emails or clicking on links in messages you didn’t initiate. If you don’t know who sent you an email, you should never open the attachment or click the link.

Pharming Attacks

Pharming attacks are a deceptive form of cyber attack that involves redirecting users from legitimate websites to fake ones, often with the goal of stealing sensitive information, such as login credentials or financial data. Cybercriminals achieve this by exploiting vulnerabilities in the Domain Name System (DNS) or by installing malicious software on a user’s device.

Fraudulent websites are often created to look exactly like legitimate ones, making it hard for users to tell the difference. When users submit their personal information on these fake sites, attackers can steal it and use it for harmful activities like identity theft or unauthorized transactions.

Some security measures are-

  • Regular Software Updates: Keep all your software, including your operating system, antivirus software, and browser, updated with the latest patches and versions. These often contain security upgrades that protect against the most recent known threats.
  • Secure DNS Practices: Use a secure and trusted DNS server. Some Internet…

Explained: Most common types of malware and how they can be dangerous

/in


While a virus may be the most commonly known form of malware, there are a few others that can be dangerous to your data and devices. Viruses, worms, and Trojans are three types of malicious software (malware) that can cause harm to computer systems and networks. Although they all fall under the category of malware, they have distinct characteristics and operate differently. Here, we explain the difference between viruses, worms, and Trojans and how they pose a danger to your devices.

What is a virus?

A computer virus is a type of malware that attaches itself to a legitimate program or file and replicates itself. When the infected program or file is executed, the virus is activated, and it can spread to other programs and files on the computer or network. The primary goal of a virus is to replicate and spread, causing damage to the infected computer or network.
Viruses can be spread through email attachments, infected websites, or file-sharing networks.
A virus can cause a range of problems, including slowing down the computer’s performance, corrupting files, and deleting important data. In some cases, a virus can also allow hackers to gain access to the infected computer, giving them access to sensitive data and personal information.

What is a worm?

A worm is a type of malware that is designed to spread quickly through a network by exploiting security vulnerabilities. Unlike a virus, a worm does not need to attach itself to a program or file to spread. Instead, it can replicate itself and spread from computer to computer, often without the user’s knowledge.
Worms can spread rapidly and cause widespread damage to computer networks, sometimes causing entire systems to crash. They can also be used to install other types of malware, such as spyware or keyloggers, on the infected computer. Worms can be spread through email, instant messaging, or through security vulnerabilities in software and operating systems.

What is a trojan?

A trojan, short for the trojan horse, is a type of malware that disguises itself as a legitimate program or file. Once the user installs or executes the trojan, it can perform a variety of malicious actions, such as stealing data, modifying files, or installing other…
