Electronic mail, most commonly called email or e-mail since around 1993
E-mail is one of the most widely used forms of communication today.
E-mail is faster and cheaper than traditional postal mail, but at least when you seal that envelope and stick a stamp on it, you can have some confidence that only the intended recipient will open it.
With e-mail, however, your message could be intercepted midstream, and you might never realize it. You have to take steps to secure and protect your e-mail messages.

  1. 1. Email Security Presented by Salman Memon 2k12-IT-109
  2. 2. What is Email ? • Electronic mail, most commonly called email or e-mail since around 1993 • E-mail is one of the most widely used forms of communication today. • E-mail is faster and cheaper than traditional postal mail, but at least when you seal that envelope and stick a stamp on it, you can have some confidence that only the intended recipient will open it. • With e-mail, however, your message could be intercepted midstream, and you might never realize it. You have to take steps to secure and protect your e-mail messages.
  3. 3. What is Email Security ? • Email security give the surety about secure email. • Email security has become a hot topic in Information Technology , but it can pose a number of security threats, both with incoming and outgoing messages. • Email security is a priority for all businesses, with the growing threat of hackers, viruses spam, phishing and identity theft, as well as the need to secure business information.
  4. 4. Email security cont.. • Email security is dealing with issues of unauthorized access and inspection of electronic mail. This unauthorized access can happen while an email is in transit, as well as when it is stored on email servers or on a user computer. • Email has to go through potentially untrusted intermediate computers (email servers, ISPs) before reaching its destination, and there is no way to tell if it was accessed by an unauthorized entity.
  5. 5. WHAT DOESEMAILSECURITYINVOLVE? • The three main principles of Information Security involve • Maintaining the confidentiality, • Integrity, and • Availability of information resources. • These three principles can be directly applied to the area of email security as well. • Confidentiality of email involves making sure it is protected from unauthorized access • Integrity of email involves a guarantee that it has not be modified or destroyed by an unauthorized individual. • Availability of email involves ensuring that mail servers remain online and able to service the user community. • A weakness in any one of these three key areas will undermine the security posture of an email system and open the door to exploitation.
  6. 6. How to secure Email • Web browsers maintain a history of visited sites, and a cache of browser data that help them load frequently visited pages more quickly. The history and cache may also inadvertently expose your e-mail messages. When you are done using your Web mail, you can go into the settings for the browser and clear out the cache. • Better yet, use private browsing. The most popular Web browsers--such as Internet Explorer, Firefox, and Chrome-- have an option to surf the Web using a private or anonymous mode. When you use the private browsing mode, your entire Web session is more secure, since no data is retained in the history or cache
  7. 7. How to secure email cont.. • Privacy mode or "private browsing" or "incognito mode" is a privacy feature in some web browsers to disable browsing history and the web cache. This allows a person to browse the Web without storing local data that could be retrieved at a later date
  8. 8. WHAT ARE THE THREATS TO EMAIL SECURITY? • Viruses • SPAM • Clicking on links attached in Emails • Open attachments if the sender is unidentified
  9. 9. THANK YOU
