For sure wala kang Network Protection kaya ka na DDOS. Makakatulong ang Firewall para hindi ka ma DDOS.

Install ka ng IPS. Hindi enough yung firewall lang. I assume na web yung server mo? Kahit nakablock pa sa firewall yung ibang ports, makakatagos pa rin yung mga application (layer 7) attacks - sql injection, malfored tcp, cross scripting- etc.

Pero ang pinakaimportante, secure mo yung OS mo. Ipatch ang dapat i-patch.

patay tau dyan, windows pala OS mo. kong sa linux kasi sa iptables create ka lang ng rules na 100 concurrent connection per IP para di mo maramdaman yong epekto ng DDOS.

Matagal na version: Nope hindi naman sya katagalan na version at hindi lahat alam ang loophole. Pag napasok ng attack ang Windows Server it means kulang sa Security Patches, hindi updated ang anti-virus at hindi na manage ng husto ang network.

Mas secure ang Linux/Unix: hindi ako agree sa pananaw na ito. Ang security ng isang server ay depende sa abilidad ng Administrator. Kung Windows ang pag uusapan, dapat merong budget na kaakibat. Halos lahat ng Enterprise solutions ay mataas ang cost.

kung general na pananaw kahit anong server or OS pa yan e prone yan sa atake even PENTAGON the most secured e naatake sila

Wala pa ring tatalo sa appliance firewall with subscription mga kapatid (ex. juniper and cisco) pero tama rin si boss telesforo kahit anong ganda ng gamit, nasa sys admin pa rin yan pano nya ihahandle yong network/data center nya.

Hello TS,

Hindi ako IT Security and hindi rin ako taga-Fortinet, pero mas maganda siguro bumili ka ng Fortigate Firewall, mi UTM (Unified Threat Management) features like AntiVirus, IPS (Intrusion Prevention System), Web Filtering, Anti-spam, etc. Mi VPN and Virtual IP din. Kaso lang mi yearly subscription pero okay so far yong mga products nila. Mi pang SMB or Enterprise at maraming awards.

http://www.fortinet.com/press_releases/2013/unified-threat-management-computerworld-award.html

Nirerecommend ko lang kasi ito yong ginagamit namin sa mga customer namin. So far walang nangyaring intrusion sa mga servers nila after a year and still. Linux-based firewall pala ito.

Mali ka na naman, vulnerable ang PENTAGON sa cyber attack dahil sa mga confidential documents. If ever itanong ko sayo ano ang mas secured na server OS, kaya mo ba itong i tighten ang security nya? Or based lang sa kwento ng mga nakausap mo?

Uulitin ko ha, ang SECURITY ng isang server is nasa ADMIN. Wala sa OS mismo. Lahat ng OS merong vulnerabilities.

Pwede pero anong point? Same old story lang if di mo maayos yung security ng server mo.
