Uru nke imejuputa IDS.

Ịmejuputa Sistemụ Nchọpụta Intrusion (IDS) nwere ike inye ọtụtụ uru maka ndị otu na-achọ ịkwalite nchebe cybersecurity ha.

Firstly, an IDS can help detect and prevent unauthorized access to the network. By monitoring network traffic or individual hosts, an IDS can identify suspicious or malicious activity and alert the organization to threats. This early detection can help prevent data breaches, unauthorized access to sensitive information, or the spread of malware within the network.

Nke abuo, IDS nwere ike inye nghota bara uru n'ime udi mbuso agha na adighi ike na-echuso netwọkụ otu ahụ anya. Site n'ịtụle ụkpụrụ na mbinye aka nke mwakpo achọpụtara, otu dị iche iche nwere ike ghọta nke ọma adịghị ike netwọk ha wee mee ihe dị mkpa iji wusie usoro nchekwa ha ike.

Na mgbakwunye, IDS nwere ike inye aka na nzaghachi ihe omume yana nyocha nyocha. Mgbe ihe nchekwa mere, IDS nwere ike ịnye ndekọ zuru ezu na ozi gbasara mwakpo ahụ, na-enyere òtù dị iche iche aka ịmata isi mmalite, chọpụta mmetụta ọ kpatara, ma mee ihe kwesịrị ekwesị iji belata mmebi ahụ.

Ọzọkwa, imejuputa IDS nwere ike inyere òtù dị iche iche aka irube isi n'usoro iwu chọrọ yana ụkpụrụ ụlọ ọrụ. Ọtụtụ ụkpụrụ na usoro, dị ka Kaadị Payment Card Industry Data Security Standard (PCI DSS) ma ọ bụ Health Insurance Portability and Accountability Act (HIPAA), chọrọ ka òtù dị iche iche nwee ikike nchọpụta mbubata iji chebe data nwere mmetụta.

N'ozuzu, IDS bụ akụkụ dị oke mkpa nke atụmatụ cybersecurity zuru oke. IDS nwere ike ịkwalite nchebe cybersecurity nke otu ụlọ ọrụ site na ịchọpụta na igbochi ohere ịnweta netwọkụ na-enwetaghị ikike, na-enye nghọta maka adịghị ike, na-enyere aka na nzaghachi ihe omume, na ịgba mbọ hụ na nrube isi nke usoro iwu.

Otu akụkọ si ỌkụEye highlighted new trends for 2019, in which hackers are causing significant disruptions. They disrupt businesses, steal personally identifiable information, and attack routers and switches. I believe this new trend will continue into the foreseeable future.
