Generally, it is considered good practice to remove unused objects in SmartConsole, as each time the policy is installed, the gateway and management server use resources and, importantly, time to verify and apply the policy.<\/p>\n<h4>3.4 How is the Threat Prevention policy configured? <\/h4>\n<p>\nFirst, Check Point recommends placing IPS in a separate profile and creating separate rules for this blade. <\/p>\n<p>For example, if an administrator believes that the DMZ segment should only be protected by IPS, then to prevent the gateway from wasting resources on processing packets by other blades, a specific rule needs to be created for this segment with a profile that includes only IPS.<\/p>\n<p>Regarding profile configuration, it is recommended to set it up according to best practices in this <noindex><a rel=\"nofollow\" href=\"https:\/\/downloads.checkpoint.com\/dc\/download.htm?ID=54842\">document<\/a><\/noindex>(pages 17-20).<\/p>\n<h4>3.5 How many signatures are in Detect mode in IPS settings? <\/h4>\n<p>\nIt is strongly recommended to review the signatures with the understanding that unused ones should be disabled (for example, signatures for exploiting Adobe products require a lot of computational power, and if the client does not have such products, it makes sense to disable those signatures). Moreover, switch to Prevent instead of Detect wherever possible, because the gateway spends resources processing the entire connection in Detect mode, while in Prevent mode, it immediately drops the connection and does not waste resources on full packet processing.<\/p>\n<h4>3.6 What files are processed by the Threat Emulation, Threat Extraction, and Anti-Virus blades?<\/h4>\n<p>\nNincs \u00e9rtelme emul\u00e1lni \u00e9s elemezni olyan kiterjeszt\u00e9si f\u00e1jlokat, amelyeket a felhaszn\u00e1l\u00f3k nem t\u00f6ltenek le, vagy amiket feleslegesnek tartanak a h\u00e1l\u00f3zatban (p\u00e9ld\u00e1ul a bat \u00e9s exe f\u00e1jlokat k\u00f6nnyen le lehet tiltani a Content Awareness blade seg\u00edts\u00e9g\u00e9vel a t\u0171zfal szintj\u00e9n, \u00edgy a gateway er\u0151forr\u00e1sai kevesebb m\u00e9rt\u00e9kben terhel\u0151dnek).
