Plesk<\/a> erbjuder alternativet att konfigurera brandv\u00e4ggen f\u00f6r webbapplikationer (plesk modsecurity) i administrationsmenyn.<\/p>\n

Vad \u00e4r modsecurity?<\/h2>\n

Plesk Modsecurity \u00e4r en webbapplikation Brandv\u00e4gg<\/a>, dvs. en brandv\u00e4gg som blockerar tillg\u00e5ngen till webbprogram som t.ex. System f\u00f6r inneh\u00e5llshantering.<\/a> (wordpress<\/a>, joomla<\/a>etc.) eller andra program och f\u00f6rhindrar k\u00e4nda attacker.<\/p>\n

F\u00f6rdelen med modsecurity \u00e4r m\u00f6jligheten att f\u00f6rst analysera \u00e5tkomsterna och d\u00e4refter definiera vilka \u00e5tkomster som \u00e4r legitima och vilka som m\u00e5ste avvisas direkt.<\/p>\n

Det \u00e4r naturligtvis om\u00f6jligt att st\u00e4lla in allt sj\u00e4lv, men det finns leverant\u00f6rer som tillhandah\u00e5ller f\u00e4rdiga regler, varav vissa \u00e4r levande, och som d\u00e4rmed kan reagera direkt p\u00e5 aktuella hot.<\/p>\n

Om det till exempel sker en ny attack mot ett visst inneh\u00e5llshanteringssystem uppdaterar dessa leverant\u00f6rer sina regler och modsecurity kan d\u00e5 blockera dessa \u00e5tkomster innan en infektion uppst\u00e5r.<\/p>\n

F\u00f6r Plesk-anv\u00e4ndare \u00e4r detta ett bra program f\u00f6r att stoppa de flesta k\u00e4nda attacker mot ditt program.<\/p>\n

Tillsammans med en brandv\u00e4gg som filtrerar och blockerar IP-adresserna kan du skydda din server p\u00e5 ett bra s\u00e4tt.<\/p>\n

Externa l\u00f6sningar<\/h2>\n

En extern brandv\u00e4gg som t.ex. Cloudflare WAF<\/a> fungerar p\u00e5 samma s\u00e4tt med delvis samma regler, men ger m\u00f6jlighet att avv\u00e4rja attacker innan de n\u00e5r fram till servern. Ett optimalt skydd skulle d\u00e4rf\u00f6r vara ett Web Application Firewall fr\u00e5n Cloudflare<\/a> eller Imperva\/Incapsula och sedan endast anv\u00e4nda s\u00e4rskilda regler p\u00e5 servern. Detta sparar processorkraft och snabbar upp sidan avsev\u00e4rt.<\/p>\n

Alternativt kan du naturligtvis st\u00e4lla in modsecurity som en omv\u00e4nd proxy och d\u00e4rmed anv\u00e4nda alla andra webbservrar \u00e4n Apache.<\/p>\n

Hur installerar man Plesk modsecurity?<\/h2>\n

Som administrat\u00f6r klickar du bara p\u00e5 Inst\u00e4llningar och v\u00e4ljer Web Application Firewall (modsecurity) d\u00e4r.<\/p>\n

\"plesk_admin_modsecurity_settings\"<\/a>I Plesk-menyn kan du v\u00e4lja den leverant\u00f6r fr\u00e5n vilken du vill anv\u00e4nda reglerna. OWASP- eller Atomic Basic-reglerna \u00e4r gratis. Dessa har dock nackdelen att de s\u00e4llan uppdateras, eller i OWASP:s fall att reglerna \u00e4r f\u00f6r starka, s\u00e5 att det finns problem med till exempel wordpress, som man d\u00e5 m\u00e5ste ta bort f\u00f6rst.<\/p>\n

H\u00e4r finns fortfarande de billiga comodo-reglerna som ger ett bra skydd mot alla hot. Licensen m\u00e5ste dock alltid uppdateras.<\/p>\n

Den som \u00e4r f\u00f6r lat kan d\u00e4rf\u00f6r helt enkelt anv\u00e4nda Atomic-prenumerationsreglerna som ger ett levande skydd. H\u00e4r m\u00e5ste man dock notera att detta inte heller \u00e4r helt sant, eftersom webbservern m\u00e5ste laddas om och d\u00e5 uppst\u00e5r problemet med 502 bad gateway igen.<\/p>\n

Praktiskt \u00e4r Atomic Professional-skyddet som \u00e4r tillg\u00e4ngligt tillsammans med Cloudflare i paketet. H\u00e4r kan du enkelt ta bort brandv\u00e4ggen f\u00f6r webbapplikationer fr\u00e5n Plesk och byta alla dina dom\u00e4ner till Cloudflare som en extra skyddsmekanism.<\/p>\n

Problemet h\u00e4r \u00e4r att du bara kan skydda underdom\u00e4ner, s\u00e5 din webbplats borde bara vara tillg\u00e4nglig under www.ihrefirma.de och inte under yourcompany.com. Alternativt kan du som Cloudflare-partner ocks\u00e5 anv\u00e4nda Cloudflares namnservrar och p\u00e5 s\u00e5 s\u00e4tt erbjuda fullst\u00e4ndigt skydd.<\/p>\n

Eftersom licenspriserna f\u00f6r Plesk och till\u00e4ggsprogrammen st\u00e4ndigt h\u00f6js p\u00e5 ett o\u00f6versk\u00e5dligt s\u00e4tt b\u00f6r man som leverant\u00f6r kanske ocks\u00e5 t\u00e4nka p\u00e5 en extern licensiering.<\/p>\n

Det finns intressanta l\u00f6sningar direkt fr\u00e5n atomicorp, eller ett annat s\u00e4tt att aktivera mod_security p\u00e5 servern, eller till och med anv\u00e4nda ett externt skydd som Cloudflare.<\/p>\n

En bra ers\u00e4ttning f\u00f6r Plesk p\u00e5 grund av de os\u00e4kra integritetsfr\u00e5gorna med alla plugins skulle vara en tysk tillverkare av den popul\u00e4ra adminpanelen \"Liveconfig\".<\/p>\n

Plesk-till\u00e4gg med st\u00f6d f\u00f6r ModSecurity<\/h2>\n

Det finns n\u00e5gra till\u00e4gg f\u00f6r Plesk med vilka du kan s\u00e4kra servern. Dessa inkluderar \u00e4ven modsecurity-regler f\u00f6r att skydda sig mot k\u00e4nda attackm\u00f6nster.<\/p>\n

Imunify360<\/h3>\n

F\u00f6rutom sitt eget operativsystem erbjuder Cloudlinux \u00e4ven s\u00e4kerhetsl\u00f6sningen Imunify360. Detta erbjuder ett mycket brett utbud av funktioner f\u00f6r alla s\u00e4kerhetsomr\u00e5den p\u00e5 servern. Brandv\u00e4ggen \u00f6vervakar protokollen och blockerar vid behov IP-adresser som t.ex. ansluter f\u00f6r ofta med falska inloggningsuppgifter, som finns p\u00e5 en sp\u00e4rrlista eller som vill komma \u00e5t med k\u00e4nda attackm\u00f6nster. Man kan ocks\u00e5 helt enkelt aktivera ett DoS-skydd och skanna alla filer efter k\u00e4nd skadlig kod och delvis rensa dem. Dessutom finns det en s\u00e5 kallad KernelCare-funktion som automatiskt uppdaterar Linuxk\u00e4rnan utan att systemet beh\u00f6ver startas om. Till\u00e4gget kan erh\u00e5llas direkt fr\u00e5n Cloudlinux och kostar mer \u00e4n Plesk sj\u00e4lvt.<\/p>\n
