Guidelines fr Assessment Activities The assessr is required t devise assessment briefs and marking schemes fr the skills demnstratins, examinatin papers, marking schemes and utline slutins fr the examinatin. In devising the assessment briefs and examinatin papers, care shuld be taken t ensure that the learner is given the pprtunity t shw evidence f achievement f ALL the learning utcmes. Assessment briefs may be designed t allw the learner t make use f a wide range f media in presenting assessment evidence, as apprpriate. Quality assured prcedures must be in place t ensure the reliability f learner evidence. Learning utcmes 3 and 5 are assessed by bth examinatin and skills demnstratin. It is intended that knwledge f the cncepts invlved is assessed by examinatin and that the learner demnstrates practical skills and techniques in the skills demnstratin.

(It is nt necessary t gain access t the vulnerable machine, nly t demnstrate the techniques an attacker might use) Using Access Cntrl Lists t limit access t cmmn services, e.g. HTTP FTP ICMP Evidence fr this assessment technique may take the frm f written r digital evidence, r any cmbinatin f these Any audi, vide r digital evidence must be prvided in a suitable frmat. All instructins fr the learner must be clearly utlined in an assessment brief. Exam 40% 2 Hurs (1,2,3,4,5,12) Devise an exam paper, with 4 structured questins, where the student must answer all questins. Questins shuld cver the fllwing areas: Cmmn terminlgy and key cncepts in Netwrk Security(1) e.g. Access cntrl, Attack methdlgies Identify different attacks that are perfrmed n a Netwrk, explain hw they are achieved(2,3) Explain the varius methds f prtectin that are available, including apprpriate plicies(4,5) Describe the imprtance f auditing and cmpliance in Netwrk Security.(12) Structured questins are divided int a number f related parts and generally require the learner t demnstrate mre in-depth knwledge and understanding f a tpic.
