Policy track

Background

• Protection of personal data

• Compliance to regulations

• The Personal Data Act

• The Personal Data Regulations

• Security management(Section 2-3. )

• Risk assessment(Section 2-4. )

• Efficiency, etc.

• Improve governance and controlI regarding actual threats

• Proportionality requirements – extent and type of business

PDA – def’s

Section 2 Definitions

For the purposes of this Act, the following definitions shall apply:

1)personal data: any information and assessments that may be linked to a natural person,

sensitive personal data: 8) information relating to

a) racial or ethnic origin, or political opinions, philosophical or religious beliefs, b) the fact that a person has been suspected of, charged with, indicted for or convicted of

a criminal act, c) health, d) sex life, e) trade-union membership.

Sensitive personal data shall be processed and stored in secure

areas where only authorized users are granted access. A

business can create multiple secured zones depending on

demand.

Mapping standpoint – IS Audit

• Based on ISO 27001 (Apendix A)

• regulatory requirements (PDA, The Copyright Act)

• ”Best Practice” (ISACA, ISF, DND, NIST, vendors

recommendations, etc)

• Checklists that reflect the above

• Report

Typical IS audit conclusions

The technical security of the existing solutions is mostly satisfactory, and provides relevant security against traditional threats.

A Data Inspectorate audit would have resulted in clear orders that would have to be fulfilled within six months in line with the recommendations in our report.

Some essential governing documents are missing, e,g.

o security policy (incl. security objectives and strategy),

o IT strategy

o continuity and contingency plans for IT.

Outsourcing contracts are inadequate with respect to information security, including missing SLA.

i.e – “The terrain can be good - but the map is missing”

19

20

IS Audit: Overall recommendations

Establish Security Policy based on ISO 27002, and implement it,

including a selection of procedures.

Establish the role of Chief Security Officer (CSO) and formally

anchor the responsibility for information security in senior

management .

Perform risk assessment of systems with personal data with

respect to confidentiality, integrity and availability.

Develop an overview of the Personal Data that are processed

Establish a satisfactory security architecture based on the

concept of security levels

Develop BCP (Business Continuity and Contingency Plans) for

ICT infrastructure.

Noen risikoer ifht teknologi

Mobility / BYOD rises significant risks Moving boundaries / Security Barriers

Private entity that is often filled with company information

Kompleksitet kan være fiende

o Som følge av unødvendig funksjonalitet

o Som følge av for mye ”Teknologi fokus”

Stadige endringer/ teknologi skifte en trussel

o Gir mindre tid for utvikling av effektive sikkerhetstiltak

Mangelfull/manglende IT-/Teknologi strategi en trussel

o Kan gi tilfeldige anskaffelser

o Være kostbart

o IT-strategi må være forretningsforankret

Unngå ”For mye sikkerhetsteknologi”

o Sett tiltakene etter ROS vurdering

Unngå risikopreget konfigurasjon

o Eksempel: klienter og servere i samme segment/ regime, i kombinasjon med tilgang til lokal administrator på klient/PC – samt tillate BYOD uten ansvarliggjørende tiltak

Security with a system – document structure

Why

What

How

1) Security Policy defines the goals, purpose,

responsibility and overall requirements. Governing

document

2) Guidelines for information security. Defines what should be done to comply with the

established policy. Governing document – ISO 27k

structure

3) Standards and procedures Contain detailed guidelines for the implementation

of security. Accomplishing and controlling

documents

27

Security put in system

Inspectorate often get questions about how the

company l can adapt to the Data Inspectorate's

requirements for information security. Among

other ¸it is Asked about the relationship with ISO

standards. The regulation is based on ISO

standards . Chapter 2 of the Personal Data

Regulations (The Information Security chapter) is

based on and have the same systematics as the

ISO standard 17799. The standard is more

exhaustive and is another useful tool for

enterprises. The standard series consist of two

parts. The first part is translated into Norwegian.

The standard can be obtained by contacting

Pronorm.

Definition of risc management – a simple definition

Risk management is about determining acceptable risk, making

risk assessment and prioritize security measures. This is the

senior manager's responsibility.

Risikohåndtering – fire kategorier:

• Å unngå – Å gå ut av de aktivitetene som er en kilde til risiko

• Å redusere – Tiltak blir iverksatt for å redusere sannsynligheten for eller konsekvensen av risikoen, eller begge deler

• Å dele – Å redusere risikoens sannsynlighet eller konsekvens ved å overføre, eller på annen måte dele en bit av risikoen med andre

• Å akseptere – Ingen tiltak blir iverksatt for å påvirke risikoens sannsynlighet eller konsekvens

BIA - Impact assessment of outage

The business must find the optimal "point" to restore IT

services by balancing the costs of recovery and the costs /

losses from downtime.

BIA provides downtime costs and evaluation of the recovery

strategy provides

costs of recovery.

• Informasjon og dets medium som skal kontrolleres og vedlikeholdes av virksomheten

“Documented information”

• Maksimal tid en aktivtet kan stoppe til driften hemmes mer enn akseptabelt

“Maximum Acceptable Outage”

• Forhåndsbestemt tid innen aktivtet må være gjenopptatt eller ressurser være gjenopprettet.

“Recovery Time objective (RTO)”

• Maksimalt tap av data eller minimum data som må kunne gjenopprettes

“Recovery Point Objective (RPO)”

• Handling for å korrigere et oppdaget avvik “Correction”
