Email Security

The use of emails has always been increasing ever since its inception in the 1960s. Business communication, circulation of academic information, conveying personal information – almost everything is passed on between individuals or organizations via emails mainly for either or all of the following reasons:

  • Emails are faster.
  • Emails are reliable.
  • Emails ensure that the information reaches the end recipient and, if not, notifies the sender about it.
  • There is no scope of data loss with emails.
  • Emails are an excellent means of recording information chronologically.

Are Emails Secure?

On the surface, there is nothing to be concerned about in email communication. The accounts of both the sender and the receiver are self-operated and locked by passwords which only both of these parties know. However, with the advancement of useful technology occurs an equal (if not higher) rise in technology which brings vicious attackers and hackers into the picture.

What Is Phishing?

Phishing attacks are just like fishing in a river where a person tries to get hold of a fish by giving it a believable bait of a bread crumb or any similar bit of food. However, in phishing attacks, the fishes are the netizens, and the fishermen are the cyber attackers. Phishing attacks are most commonly circulated via email messages. In such attacks, an unexpected mail from a seemingly credible source asks the receiver to take specific immediate action (such as paying unpaid dues or claiming a reward) by clicking on an attached link or downloading a file. But these are impersonating emails taking the user to fake websites created by the attacker. And often, these install malware into the computers of users. These attacks also happen in other forms like through voice messages (Vishing), SMS frauds (Smishing), attacks targeting the big shots of an organization from whom the profits can be maximum (Whaling) or creating a replica of a website to win the trust of an unsuspecting user (Pharming).

What Is Malware?

Malware is another means used by attackers to install corrupt files and software into the computer systems of users without their permission or against their will. Often malware operates secretly and steals the private information of users without their knowledge. This information is then accessed by the attacker who either uses the data to blackmail the victim, launch a sextortion campaign, or sell the stolen details at a high price in the dark market. Its types include:

  • Ransomware – which locks the system of the user or encrypts files until the demanded ransom is paid.
  • Spyware – which launches spying software into the computer and steals data.
  • Scareware – which attempts to extract user information by instilling fear in them.
  • Adware – where malware gets downloaded via attacker-created fake advertisements.

What Is Email Security?

Email security is the process of shielding email accounts from the attacks of vicious hackers. It refers to the means employed by a user, an organization, or an information network to keep themselves secure from these phishing attempts and malware attacks.

How To Ensure Email Security?

Email security can never be a fool-proof plan as the attackers always manage to find some loophole even in the most sophisticated methods of protection. However, minimizing such attacks is the objective, and this can be achieved by adopting the following measures:

  • Setting strong passwords: Strong passwords with alphanumeric characters and symbols are highly recommended. It’s always more important to have secure passwords instead of easy to remember passwords.
  • Changing passwords from time to time: Using the same password for too long makes you more vulnerable to hacking attempts of attackers. Hence it is always advisable to change passwords from time to time. Also, having different passwords for different accounts is a smarter decision than otherwise.
  • Having a good antivirus installed: Antivirus software creates a layer of protection against all types of viruses and malware trying to attack your devices. It is a must to have an antivirus when you visit multiple websites on the Internet or install external devices and disks into your computer.
  • Having anti-spam filters: Anti-spam filters ensure that spam emails or messages do not show up in your mailbox, thus protecting your system from the malicious emails sent by attackers. It also saves you a lot of time and energy that gets wasted otherwise in opening those emails.
  • Using only updated software: Software developers update software from time to time to incorporate patches and other improvements to make the software secure and more efficient. Not updating one’s software to the latest version is sending an invitation to attackers to steal your files.
  • Being wise on the web: With everything said and done, the most frugal tip remaining is to be careful on the Internet. One must have a skeptical mind and halt before impulsively clicking on links and pop-ups. A click takes hardly a second, but often its after-effects cost millions of dollars!

Since one cannot do away with emails, one needs to find ways and means of doing away with the threats to email security. Protecting yourselves on the web is not easy but also not unachievable. Taking specific preventive measures goes a long way in keeping attackers and malware away.

Microsoft Exchange Servers Best Practices to Ensure a Robust Email Security Posture

Microsoft Exchange Server primarily helps organizations send, receive, and store organizational email messages. However, there are many more functions that Microsoft Exchange Server provides to its users. It is deployed on the Windows Server Operating System and is primarily used for business purposes.

A few of the leading collaborative features are calendaring and integrating with other Microsoft applications. Microsoft Exchange Server is widely used by organizations around the world, which makes it highly vulnerable to malicious actors, who are always on the lookout to exploit one vulnerability or another. For instance, earlier this year, Chinese threat actors were reported to exploit vulnerabilities of the Exchange Server to attack organizations throughout the United States that were using Exchange Server for their email operations or other activities.

6 Tips for Maximum API Security

With API security, you’re not just securing your data but the strength of the infrastructure as well. When hackers exploit the vulnerabilities in the API and gain access to the entire network, they engage in privilege escalation and employ different kinds of attacks and compromise the most sensitive data. This could lead to huge revenue losses and long-term damage to the firm’s reputation, all of which has a better probability of being avoided with due efforts made in API security.

Email Security Basics – 10 Aspects to Keep in Mind on How to Secure Your Mail Server

Email Security Basics – 10 Aspects to Keep in Mind on How to Secure Your Mail Server

While website security tools secure the data that passes from server to browser, email security tools prevent unauthorized access to email accounts, content, and communications. In general, the safety of email servers tends to be limited to problems with messaging and the application of security measures that have more to do with anti-virus and anti-spam protection. If a business is dependent solely on a platform such as Gmail or MS Outlook, it does not need to focus on protecting email servers. However, when one decides to implement and maintain a dedicated email server, one must employ spam protection, phishing protection, ransomware protection, and other advanced safeguards against email threats.

Importance of Zero-Trust Model For Email Security

The reports of the past five years show that around 80% of all cyber-attacks are impersonating social engineering attacks. Today, most email attacks are malware-less to avoid setting off malware scanning alarms. The primary aim of adversaries is to gain the target’s trust by impersonating some legit entity or user. As the emails do not contain any malicious content, they can easily bypass the email security defenses.

The situation has even worsened globally during pandemic times as most of the phishing attacks are coronavirus-themed. Malicious actors take advantage of the employees working from home with less secure connections and endpoint devices.
