●Adopt yakatsaurirwa ma frequency mabhendi kuti uzviparadzanise nemaoko kuwanikwa kwemidziyo ine isina rezinesi frequency bhendi.
●Vashandisi vanoshandisaIWAVE tactical lte mhinduronharembozha uye makadhi eUIM kudzivirira kupinda kwemidziyo zvisiri pamutemo.
Network Layer
●Iyo Milenage algorithm uye mashanu-tuple authentication paramita anoshandiswa kuwana mbiri-nzira yechokwadi pakati peEU netiweki.
Kana terminal ikapinda kunetiweki, network inosimbisa iyo terminal kudzivirira vashandisi zvisiri pamutemo kuti vasvike.Panguva imwecheteyo, iyo terminal ichasimbisawo network kudzivirira kupinda kune phishing network.

Application Layer
●Kana vashandisi vasvika, chengetedzo yechokwadi inoiswa padanho rekushandisa kudzivirira kupinda kwemushandisi zvisiri pamutemo.
●Mushandisi data anogona kushandisa iyo IPSEC nzira yekuona mushandisi kuchengetedzwa kwedata.
●Kana dambudziko rawanikwa panguva yekushandisa, mushandisi ane dambudziko anogona kumanikidzwa kuenda kunze kwenyika nekuronga mashandiro akadai sekumanikidzwa kubviswa uye kuuraya kure.
Network Security
●Iyo yakavanzika network bhizinesi system inogona kubatana kune yekunze network kuburikidza nefirewall zvishandiso kuti ive nechokwadi chekuti yakavanzika network inodzivirirwa kubva kunze kwekurwiswa.Panguva imwecheteyo, iyo yemukati topology yetiweki inodzivirirwa uye yakavanzika kudzivirira kuratidzwa kwetiweki uye kuchengetedza network kuchengetedzwa.
