Packet inspectionem altum (Dpi)Est technology in network packet sectoribus (npbs) ad inspicere et analyze contentis in network packets ad granuloso gradu. Is involves scrutandis payload, capitis et alia protocol-specifica notitia intra packets ad quaestum detailed insights in network negotiationis.
DPI vadit ultra simplex header analysis et praebet altum intellectus notitia fluit per retis. Non concedit in-profundum inspectionem application layer protocols, ut HTTP, FTP, SMTP, VoIP, aut video effusis protocols. Per scrutandis ipsam contentus intra packets, dpi potest deprehendere et identify specifica applications, protocols, vel etiam specifica notitia exemplaria.
Insuper et hierarchica analysis de fontem oratio, destination oratio, fonte portus, destination portubus, et protocol types, dpi etiam adiungit applicationem-layer analysis ad identify variis application et contenta. Cum 1P packet, TCP et UDP data fluxus per Bandwidth Management System secundum dpi technology, quod ratio legit in 1p packet onus ad reorganize ad applicationem accumsan informationem in OSI in totam applicationem progressio, ita ut ad a negotiationis secundum ordinem ad procuratio consilium, ita ut ad a negotiationis secundum ad Policy defined in ratio.
Quid DPI opus?
Traditional Firewalls saepe deest Power to perform perfectam verus-vicis checks in magna volumina negotiationis. Ut technology progreditur, dpi potest praestare magis universa compescit ut reprehendo capitis et data. Typice, firewalls cum intrusion Dependement systems saepe uti DPI. In mundo ubi digital notitia est paramunt, omnis fragmen digital notitia traditus est in Penitus in parva packets. Hoc includit email, nuntios missi per app, websites visited, video colloquia et magis. Insuper in ipsa notitia, haec facis includit metadata quod identifies in negotiationis fontem, contentus, destination et alia notitia. Cum packet filtering technology, data potest continue monitored et managed ut sit transmittantur ad ius est. Sed ut network securitatem, traditional packet filtering est procul satis. Quidam de pelagus modi abyssi packet inspectionem in Network Management sunt enumerantur infra:
Matching modus / signature
Quisque packet est sedatus ad par apud database de notum network impetus per firewall cum intrusion deprehensio ratio (IDs) capabilities. IDs searches sciri malicious specifica exemplaria et disables negotiationis cum malicious exempla sunt. In incommodum ad matching consilium est quod solum applicat ad subscriptionibus quae sunt updated frequenter. Praeterea, hoc technology non solum defendere contra notum minis vel impetus.
Protocol Exceptio
Cum Protocol Exceptio ars non solum permittit omnia notitia quod non congruit ad signature database, in protocol exceptio ars usus per IDs firewall non habet inhaerens vitiisque ex forma / signature matching modum. Instead, quod adoptat default rejectionem consilium. Per protocollum definitionem, firewalls decernere quid negotiationis debet licere et protegat in network a ignotum minis.
Principium Preficio System (Ips)
Ips solutions potest angustos ad tradenda nocivis facis fundatur in contentus, ita subsisto suspected impetus in realem tempus. Hoc significat quod si packet repraesentat notum securitatem periculo, IPS erit Proactively angustos Network negotiationis secundum defined paro of praecepta. Unum incommodum IPS est opus ad regulariter update a cyber periculum database cum details de novis minis et facultatem falsum positivarum. Sed periculum potest mitigari creando conservativa consulta et consuetudo limina, constituendum oportet baseline mores pro network components, et temporibus evaluatare monita et nuntiavit certe ad augendae et alerting.
1- et DPI (altum packet inspectionem) in network fasciculum sectorem
The "deep" is level and ordinary packet analysis comparison, "ordinary packet inspection" only the following analysis of IP packet 4 layer, including the source address, destination address, source port, destination port and protocol type, and DPI except with the hierarchical analysis, also increased the application layer analysis, identify the various applications and content, to realize the main functions:
I) Applicationem Analysis - Network traffic compositionem analysis, perficientur analysis, et fluxus analysis
II) User Analysis - User Group Dievonation, MORES Analysis, Terminal Analysis, Trend Analysis, etc.
III) Network elementum Analysis - Analysis secundum regional attributa (urbem, regio, via, etc) et basi station onus
IV) Aenean Imperium - P2P Celeritas limitandi, Qos Assurance, Bandwidth Fides, Network Resource Optimization, etc.
V) Security Assurance - DDOS Impugnat, data passim tempestas, praeventionis malicious virus impetus, etc.
2- Generalis Classification of Network Applications
Hodie sunt innumerabiles applications in Penitus, sed commune web applications potest esse exhausta canebat.
Quatenus scio, optima app recognition turba est Huawei, quod clamat ad agnoscis 4,000 apps. Protocol analysis est basic moduli de multis firewall societates (Huawei, ZTE, etc.) et quoque a valde maximus moduli, supporting ad realization of alius muneris modules, accurate et realitatem idem, et valde meliorem perficientur et reliability et in perficientur et reliability ex products. In modeling malware idem fundatur in network negotiationis characteres, sicut ego facio nunc, accurate et extensive protocol idem est etiam valde magna. Exclusa network negotiationis communis applications a comitatu scriptor export negotiationis, reliqua negotiationis ratio ad parva proportio, quod est melius malware analysis et terrorem.
Ex me experientia, quod communiter usus applications sunt classificatae secundum suum munera:
PS: Secundum personalis intellectus application ad genus, vos have ullus bonum suggestiones gratam discede nuntius rogationem
I). E-mail
II). Video
III). Ludus
IV). Officium OA classis
V). Software Update
VI). Financial (Bank, Alepay)
VII). Stocks
VIII). Social Communication (im software)
IX). Web Browsing (verisimile melius identified cum URLs)
X). Download Tools (Web Orbis P2P download, BT Related)
Deinde, quam DPI (altum packet inspectionem) operatur in an NPB:
I). Packet capere: NPB captures network negotiationis a variis fontibus, ut virgas, iter itineris, aut taps. Hoc accipit facis fluit per network.
II). Pasciculus parsing: et captum packets sunt parsed per NPB ad extract variis protocol stratis et consociata data. Hoc parsing processus adjuvat identify in diversis components in facis, ut Aer Capititores, IP capitis, onerariis accumsan capitis (eg, TCP et UDP) et applicationem layer protocols.
III). Payload Analysis, cum DPI, in NPB vadit ultra header inspectionem et focuses in payload, comprehendo ipsam data in facis. Is explorat Payload Content in-profundum, IRRESPECTUM ad applicationem vel protocollo solebat, ut extract pertinet notitia.
IV). Protocol Lepidium sativum: DPI dat ad NPB ad identify specifica protocols et applications esse solebat intra network negotiationis. Potest deprehendere et referatur protocols sicut http, FTP, SMTP, DNS, VoIP, aut Video Streaming protocols.
V). Content inspectionem: DPI permittit in NPB ad inspicere contentus de facis in propria exempla, subscriptionibus, seu keywords. Hoc dat detectionem Network minas, ut malware, virus, intrusionem conatus aut suspectum actiones. DPI potest etiam esse propter contentus filtering, coercitionem network policies, aut identifying data obsequium violationes.
VI). Metadata extraction: Per DPI, Npb excerpta pertinet metadata ex facis. Hoc potest includere notitia ut fons et destination IP oratio, portum numeris, sessionem details, transaction data, aut alia relevant attributa.
VII). Aenean fronte vel filtering: fundatur in DPI analysis, in NPB potest iter propria facis ad designandum destinations adhuc processus, ut securitas appliances, vigilantia Tools, aut analytics tabulata. Potest etiam applicare filtering praecepta abiicias vel redirect packets fundatur in identified contentus vel exemplaria.
