Network and antivirus security

UP network security

Even though UP computer network is protected against internet attacks (port filtration, Intrusion Protection system). However, only our security precautions cannot prevent mutual damage of the computers within the UP network. Therefore, we appeal to students and employees to protect their computers against computer viruses and worms.

Security of network devices

Each insufficiently secured computer represents a risk not only for its users, but also for other users of the computer network. If your computer is infected by computer viruses or worms, it can easily become a target for computer hackers who might use your device to attack other network systems. Therefore, the computer security is a mandatory requirement for every UP network user. This is based in Rector's directiveː "Every end instrument connected to UP computer network must be secured in appropriate manner, by suitable system configuration, by application of security patches, etc. Should there be an infected, insufficiently secured end instrument, computer network administrator can suspend the right to access to the UP computer network." Směrnice rektora UP B3-15/7-SR, Article 7, paragraph. 3

Employees: Computer network administrator will set up all the necessary security measures on employee's computers.

Students: All the necessary security measures must be set up by students themselves before connecting to university network.

Essential security measures:

1. You should use only updated antivirus program. Antivirus programs protect computers against most of the viruses, worms and trojan horses. Palacký University uses MS Forefront. Students are adviced to use AVG, Avastǃ or NOD32.
2. Keep your operating system updated.Microsoft publishes list of updates on their website on regular basis. Apple publishes updates for their products regularly as well. These updates deal with existing security flaws, which can by used by hackers and computer viruses.
3. Turn on your FirewallFirewall is a security gate between your computer and dangerous contents on the internet. Furthermore, firewall restricts users and programs to access your computer according to specific rules. If you're using Windows OS, your firewall should be turned on by default.

Basic antivirus security rules

1. Choose the websites you visit carefully, you can threaten your computer by visiting dubious websites voluntarily. Further, you should pay attention on what links you are actually clicking - do not click on warning windows of fake antivirus programs, fake dating sites, non-existent discounts in fictitious shops, pop-up windows posing to be social networks etc.

2. Do not respond to e-mails requesting your login details and passwords. Furthermore, do not open attachments from dubious e-mail addresses and do not click on links in spam e-mails.

3. Download only the most necessary programs (videoplayers, text editors, etc.). There is no need to download performance improvers for your computer, shareware, or so-called "entertainment" programs which are useless. Most of them are full of spyware, viruses and computer worms.

​4. Before using antispyware and other programs for removing malicious software, contact your computer network administrator first. Using more antivirus and antispyware programs at once might cause malfunction in detection of infected files. Furthermore, Windows OS might not work properly as well.

5. Update not only programs which use the internet network (Mozilla Firefox, Google Chrome, Opera, Skype, Spotify etc.), but also programs, which do not use the internet.

6. Zálohujte všechna potřebná a důležitá data. Každý z nás má v počítači data, které by rozhodně nechtěl ztratit, ať pracovní, studijní či soukromé. Doporučujeme provádět pravidelnou aktualizaci alespoň jednou měsíčně (častěji u souborů s vyšší frekvencí změn). Zálohu provádějte na jiný počítač, CD/DVD, cloudová uložiště (OneDrive, Dropbox), větší USB flash disky nebo externí disky. Váš počítač může být zavirovaný v takovém rozsahu, že dojde k poškození systému a data již nepůjde obnovit. Případně může dojít k hardwarové chybě vašeho disku, kdy o data můžete rovněž přijít.

7. Téměř každý z nás má přinejmenším jeden USB flash disk, ale málokdo si uvědomí, že právě skrze "flashky" se velice často šíří virové nákazy.

• "Jak si ověřím, že moje "flashka" není zavirovaná?"
  • otevřete si okno "Tento počítač"
  • najeďte myší nad ikonu daného USB disku a z menu přes pravé tlačítko myši zvolte prověřit antivirovým programem

8.Při podezření na zavirovaný počítač se zaměstnanci UP mohou obrátit na svého správce sítě (nejlépe prostřednictvím Helpdesku - na http://portal.upol.cz
