Network and antivirus security

UP network security

Even though UP computer network is protected against internet attacks (port filtration, Intrusion Protection system), 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.

Device security of network user

Each insufficiently secured computer represents a risk not only for its users, but also for other users of the network. If your computer is infected by computer viruses or worms, it can also become an easy target for computer hackers who might use your device to attack other systems in the network. 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 can rely on their computer network administrator, who will set up all the necessary security measures on their computers.

Students must do all the necessary security measures by themselves before connecting to university network.

Essential security measures:

1. You should use updated antivirus program. Antivirus programs protect computers against most of the viruses, worms and trojan horses. UP uses MS Forefront. Students are adviced to use AVG, Avastǃ or NOD32.
2. Keep your operating system updatedMicrosoft 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 FirewallBrána firewall vytváří ochrannou hráz mezi vaším počítačem a potenciálně škodlivým obsahem na Internetu. Firewall podle určených pravidel omezuje osobám i programům přístup do vašeho počítače. Na počítačích se systémem Windows je brána firewall ve výchozím nastavení zapnutá.

Basic antivirus security rules

1. Choose the websites you visit carefully, you 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 logins 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 programs, or "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 might cause malfunction in detection of infected files. Furthermore, Windows OS might not work properly as well.

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

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
