The 4 most important things about IT security

If you keep the four most important things about IT security, you do not have to worry anymore!

Hacker attack, virus, ransomware, worm. If you follow these four simple rules, you are armed as a company or privately against almost all IT attacks.

first Always keep the operating system up to date and update updates immediately.

With the installation of the latest updates on your computer, you will save yourself from hacker attacks and blackmail software. So you prevent a loss of data. If your operating system is outdated or no longer supported by the manufacturer, then the risk of being hacked is extremely high. Keep it always up to date. This applies to all computers, whether PC, Mac, server or your smartphone.

Any software used should be regularly checked for available updates. Very important is the ongoing check to see if your web browser is up to date. Incidentally, this is true for all browsers, whether you use Chrome, Firefox or any other browser. Check if your used plugins and extensions like Adobe Reader, Java and Adobe Flash etc. are up-to-date.

You use software from Microsoft?

My advice be sure to keep it up to date. a gateway for macro viruses. With the current updates you are well prepared.

Windows XP and Windows Vista no longer offer security updates. You should not use these versions anymore. They carry a high risk.

second Use password manager

You use the same passwords for all your accounts, whether Amazon, Dropbox, Facebook, Google, Gravatar, Instagram, YouTube, Mailchimp, Skype, Soundcloud, Tumblr, Twitter, VISA, Vimeo and WordPress, as well as mailboxes?

That’s not a good idea! If you get hacked, you lose all your access and data.

So my advice:

Do not use a password twice.

If an online service is hacked, the e-mail addresses explored by this service are also tried out with the passwords in other services. For example, an attacker could use the data from a Facebook hack to get into your other accounts.

How can you easily prevent this?

I’ll tell you if you keep reading here!

An easy and convenient way to prevent this is to manage all your passwords with a password manager. The passwords are all provided with a general key and stored in the cloud. You have concerns about the cloud? Do not worry, your data is stored safely in the cloud with the use of a good password manager in conjunction with a perfectly encrypted password.

The general key or the main password can also be generated in the following way and remember well: Just remember a sentence such as “My first trip was to the Algarve in 1999” and use the initial letters and numbers Capitalization of this sentence for the password – so arises: “MeRwadAiJ1999”. Perfect … right?

Special care should be taken to the password for the e-mail account. Since it is the most important password, you should only use it once.

Additional protection is provided by using two-factor authentication for certain online services.

3rd Regular backups of all your data

There should still be companies and individuals who, despite all risks, do not back up their data on a regular basis.

Are you or your company also part of it?

My advice:

Regular backups are indispensable for both individuals and especially for any business. If you or your company is hacked or your data has been encrypted with a ransomware software, these can be restored at any time via the backup. Prevention of data loss is one of the most important tasks in the company. The total loss of data in all companies means the loss of the business basis and ultimately the bankruptcy.

4th Use common sense

Modern cyber attacks rely on social engineering. However, in most cases the attack is subject to the vulnerability “human”. Be skeptical, for example, about transfers or debits via Paypal, which you should confirm by mail or SMS.

Prompt to open email attachments from unknown senders should under no circumstances be followed.

There is certainly a whole series of further measures to increase security in modern Internet traffic. With the aforementioned 4 rules you are already very well protected.
