The reason for this helplessness is that most of the phishing emails appear as an important notification from credible resources like Government agencies and Banks. It is difficult to identify the reliability of the source with the domain name and the email addresses from which it was propelled. Then how to resolve this issue? Well, the blog provides you 10 effective ways to get out of the disgusting server attacks. Explore and protect your servers.

    1. Ignore Emails that Request your Personal Information

    The major distinction from phishers with bankers, e-commerce or other financial companies is that the former generally personalize emails, while the latter ones do not. In phishing emails, you can see the sensational information which triggers an emergency. For example “urgent, your account details have been stolen”. This message creates an anxiety in the readers. Phishers include such messages to get instant responses from people. Always keep in mind that reputed organizations will not ask their customers for passwords or account details in an email. So if you want to check the reliability of the message, contact them by phone or by visiting their website.

    2. Grey Listing

    This anti-spam technology helps you to prevent phishing by rejecting emails from new sources by displaying temporary error messages. The legitimate servers following email standards will resend the email prior to the error message and on the other hand, spammers will not follow such protocols. So you can use this technique to filter spam emails to a great extent.

    3. SPF (Sender policy framework)

    In this method, a list of authorized emails is created in order to prevent phishing attacks on your server. You can check the data received by your email server with the prepared list of authorized emails. If the data is found mismatched, the email can be rejected. It is an effective security mechanism for stopping regular as well as spear phishing emails. SPF catches all the spoofed emails in servers while querying the authorized email sending hosts for that domain.

    4. Always Use Secure Computers

    Keep your computer secured because the phishers may use software that can record information regarding your internet activities and thereby get an access to your computer. So always remember to install antivirus software and keep it up to date to prevent such external intrusions. The firewalls safeguard the information on your computer and at the same time blocks communication from unwanted sources.

    5. Databases

    Maintaining advanced anti-spam solutions helps you feature databases of URLs and spam fingerprints which are designed to detect phishing emails. It is an effective mechanism to block regular phishing emails which target businesses.

    6. Bayesian

    Bayesian is a system which uses the statistical analysis on emails by classifying them according to its content. You can train the system with samples of both spam and legitimate emails. The periodical training can be done by the vendor or the user themselves and as long as the Bayesian filter is trained with samples of phishing emails, it remains as an effective tool to detect phishing emails.

    7. Create Awareness Among the Users

    It is important to find the common issues faced by the clients while taking defensive measures against server attacks. Identify the problems faced by the clients and educate them on the problems of phishing emails and the solutions. Most of the time the server gets hacked through the content management systems such as Joomla and WordPress which are maintained by the user. The user has to resolve the issues very quickly because the speed with which the phishing attacks are mitigated happens as swift as an arrow and a person who is educated on phishing attacks can manage it very easily.

    8. Be careful While Downloading Attachment

    Another way in which phishing happens in servers is through the attachment sent with emails. Most of the time the users are misled by the spoofed emails and they feel difficulty in rejecting or ignoring the mail which claims to be from reliable sources such as banks. Check the credibility of the email with various Anti-spam technologies and contact the officials directly by making a call. Unless you are confirmed with the source of the email, never download or open attachments, no matter who they are from.

    9. Use Accurate URLS for Banks

    Always try to save the website URLs of the bank with which are being served and type it directly when you want to visit the bank website. Phishers usually use links within emails to direct the victims to a spoofed website that has the similar web address of the bank which you want to visit. For example, the hacker may use ‘citigrouponline.com’ instead of ‘citigroup.com’. So if you suspect an email from your bank or online company as fake, do not click on any links embedded within it.

    10. Be Careful with Emails and Personal Data.

    In order to do safe transactions with the banks, always try to keep a security page on their website. Keep your PINS or passwords safe and never let anyone know your security credentials. Do not write down them and use multiple passwords for all your online accounts. Remember that the impact of phishing on business is far more insidious than just an invasion of privacy. It is used to compromise server security through social engineering and can be used to steal information, ruin reputations, steal money, disrupt computer operations, destroy important information, etc.

    Conclusion

    Phishing is one of the greatest challenges faced by the business organizations across the world. Phishers are using obfuscation techniques and the web browser vulnerabilities to create phishing scam pages that are more difficult to differentiate from legitimate sites. So the majority of the people become victims even if they are aware of the phishing scams. The best possible solution to prevent phishing attacks is to deploy the Anti-spam technologies and to keep the personal credentials safe. Remember that phishers will always use a sensational message to attract the user attention. So they are making use of the impulsive action of the reader to direct them to spoofed websites. Often mere carelessness in typing website address can cause phishing attacks on your server. Use secure systems, make regular email or account checking and follow emails or links only after confirming the reliability of the source.
