What is needed for high-quality computer protection? We all have some kind of antivirus program. But is that enough? In this text, we will explain the basic features of a firewall and give you general guidelines for its use. But what is a firewall anyway? It is your "gatekeeper", the first line of defense, protecting you from the outside world also known as the Internet. It exists as software that runs on hardware, but also as hardware itself. A firewall prevents unwanted traffic from the Internet from accessing your network and only allows responses to traffic that is approved from within. You can control which traffic is allowed and allow only selected services to communicate with the "outside world".<\/span><\/p>\n

How to set up a Firewall?<\/span><\/p>\n

To set up your Firewall, you need to define network addresses, basic firewall rules and NAT (Network Address Translation). With many firewalls today, you'll be able to get things up and running in a very short amount of time. It is up to you to choose your internal and external addresses and the services you want to use. Once the necessary definitions, firewall rules and NAT are complete, hidden rules will be created for you and your network traffic can flow. It's that easy.<\/span><\/p>\n

An interesting step forward in the domain of computer protection was made by the company\u00a0Sophos<\/a>. It was the first, and for now the only one, to connect a firewall and an antivirus program in such a way that they communicate with each other, cooperate, monitor and upgrade each other. The company Sophos went one step further. Its new generation Intercept X antivirus program is currently the only one on the market that you can install on your computer alongside an existing antivirus program. Intercept X protects against the latest threats such as ransomware and other malicious attacks.<\/span><\/p>","protected":false},"excerpt":{"rendered":"

\u0160to je potrebno za kvalitetnu za\u0161titu ra\u010dunala? Svi imamo nekakav antivirusni program. No je li to dovoljno? U ovom tekstu \u0107emo objasniti osnovne zna\u010dajke firewalla (vatrozida) i dati vam op\u0107e smjernice za njegovo kori\u0161tenje. No, \u0161to je uop\u0107e firewall? On je va\u0161 \u201evratar\u201c, prva linija obrane, \u0161titi vas od vanjskog svijeta znanog i kao Internet. Postoji kao softver koji se pokre\u0107e na hardveru, ali i kao sam hardver. Vatrozid sprje\u010dava pristup nepo\u017eeljnog prometa s interneta va\u0161oj mre\u017ei i dopu\u0161ta samo odgovor na promet koji je odobren iznutra. Sami mo\u017eete kontrolirati koji je promet dozvoljen i dopustiti samo izabranim servisima da komuniciraju s \u201evanjskim svijetom\u201c. Kako postaviti Firewall? Kako bi postavili svoj Firewall, morate definirati mre\u017ene adrese, osnovna firewall pravila i NAT (Network Address Translation). Kod mnogih dana\u0161njih vatrozida biti \u0107ete u mogu\u0107nosti postaviti stvari u vrlo kratkom vremenu. Na vama je da odaberete svoje unutarnje i vanjske adrese i usluge koje \u017eelite koristiti. Kad se jednom kompletiraju potrebne definicije, firewall pravila i NAT, skrivena pravila \u0107e biti kreirana za vas\u00a0 i va\u0161 mre\u017eni promet mo\u017ee te\u0107i. Tako je lako. Zanimljiv iskorak u domeni za\u0161tite ra\u010dunala je napravila tvrtka\u00a0Sophos. Ona je prva, i za sada jedina, povezala firewall i antivirusni program na na\u010din da oni me\u0111usobno komuniciraju, sura\u0111uju, prate se i nadogra\u0111uju. Tvrtka Sophos je oti\u0161la i korak dalje. Njen antivirusni program nove generacije \u00a0\u00a0Intercept X\u00a0 je za sada jedini na tr\u017ei\u0161tu koji mo\u017eete instalirati na va\u0161e ra\u010dunalo uz ve\u0107 postoje\u0107i antivirusni program. Intercept X \u0161titi od najnovijih ugroza poput ransomware-a i ostalih malicioznih napada.<\/p>","protected":false},"author":7,"featured_media":11858,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[285],"class_list":["post-7921","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-arhiva"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/posts\/7921","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/comments?post=7921"}],"version-history":[{"count":3,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/posts\/7921\/revisions"}],"predecessor-version":[{"id":11859,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/posts\/7921\/revisions\/11859"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/media\/11858"}],"wp:attachment":[{"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/media?parent=7921"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/categories?post=7921"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/fortuno.hr\/eng\/wp-json\/wp\/v2\/tags?post=7921"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
