How to manage Email security risks and threats.
Email is still the smartest, most productive, and extensively employed means of business communication today. Companies continue to use it to interact across the globe in a matter of minutes and connect with professionals in virtually any location, opening up a world of opportunity and possibility.
The global market for email encryption is motivated by factors such as the growing application of emails for government, corporate, and personal communication between individuals business and government agencies. These have increased the demand for email encryption to protect sensitive information from any unidentified, third party sources, or hackers. The growing loss of assets, data, and information owing to cyber-attacks and threats, such as malware, viruses, and spam, has also increased the requirement of email encryption among various business organizations.
Every company requires email security, as many modern businesses expand their reach geographically and initiate communication in every direction. Employees work remotely, national and global partners are thousands of miles away. There are many cybercriminals, government spying programs, and security threats using more than just spam and viruses to exploit vulnerabilities and steal private data during long-distance communication. There is a need for organizations to have a secure email when initiating a conversation with other companies or businesses. The communication strategies should always sync up in ways that promote secure email.
The email has become a frequent target of several attacks since it is widely used to communicate, and sometimes, with untrusted organizations. The attackers can easily exploit email to gain control over an organization, access confidential information, or disrupt IT resources to external bodies. Some common threats to email systems include:
Progressively, the attackers are fully taking advantage of emails in sending a range of attacks to organizations through the use of malware that consists of viruses, Trojan horses, and spyware. When several attacks become successful, it gives the malicious entity control over workstations and servers, which can then be used to gain access to sensitive information, monitors users’ activities, as well as perform other dangerous actions.
Spam is commonly referred to as unsolicited commercial email. It sends unwanted bulk commercial emails to companies. Such messages can easily disrupt user productivity or utilize IT resources and can be a distribution mechanism for malware. Spam also refers to the use of deceptive computer-based means to trick individuals from responding to the email-but to disclose confidential information.
Apart from hacking into a system, an attacker can use email to gather sensitive information from an organization. A conventional social engineering attack is email spoofing, in which one program successfully masquerades the other by falsifying the sender’s information in the emails to hide the real ones.
When an email appears that it comes from a legitimate source, also in actual it comes from an imposter/ fraud. It is a copy of an email header so that it seems original or factual. It is done by spammers often, and it can be accomplished by changing the “FROM:” mail address. Email spoofing can be done in different forms, but all have the same result. Spoofing can be used in spreading viruses, malicious intentions, or it is the best trick to make the user confident and release sensitive information like password, account no. or PIN no. of account. Mostly email spammers use spoofing so that receiver can get the sender’s address or possibly respond.
Phishing is a type of spam in which the sender enters its personal account information (banking data) to break an account and theft of data for fraud. Phishers can enhance credibility by spoofing to convince source address. We can take an example for better understanding; let’s say you get a false email and this email appears come from a legitimate company like eBay, Yahoo, government universities, etc. These messages look like they came from the source. These messages ask you to update your records by entering your Date of Birth, bank account number, and PIN, etc. These sites collect your data to steal your money, identity, etc. Keep in mind that legitimate companies or organizations already have your data, so they will never ask you to give all this kind of information. Whenever you consider any email as suspicious, then don’t reply, delete the email.
