Personal publication

www.nickosullivan.id.au, nicksweb.github.io and blog.nickosullivan.id.au are Nicholas O’Sullivan’s personal publishing sites.

Unless an article expressly says otherwise, opinions are Nicholas’s own. They do not represent or speak for any current or former employer, client, school, church, community organisation, vendor or other person mentioned on the sites.

General information, not professional advice

Articles are published for general information, education and commentary. They are not a substitute for advice tailored to your circumstances, including cyber security, information technology, legal, financial, medical, safety, automotive, electrical, building or other professional advice.

Technology and security conditions change quickly. Historical articles, configurations, commands, product details, prices, laws, standards and external links may no longer be current. The archived blog preserves material written between 2016 and 2022 as a historical record; it should be read in that context.

Before relying on an article, confirm current requirements, assess the risks in your own environment and obtain qualified assistance where appropriate. Only test, access or change systems, accounts, devices and domains that you own or are explicitly authorised to work on.

Accuracy and availability

Reasonable care is taken when preparing and updating content, but no guarantee is made that every statement is complete, accurate, current or suitable for a particular purpose. The sites and their content are provided as available and may be changed, corrected, suspended or removed without notice.

Nothing on these sites limits any right or remedy that cannot lawfully be excluded.

Business and promotional relationships

Nicholas operates Suburban Australia and its service brands and projects, including Suburban Secure, Townsville Computer Man and Can They Email As Me?. Articles may discuss or link to those services. Those are Nicholas’s own business interests and should be understood as such, even where the article is educational or editorial in style.

Any paid sponsorship, affiliate relationship, supplied product or other material commercial arrangement associated with particular content will be identified where relevant. A link to another organisation does not by itself imply sponsorship, endorsement or responsibility for that organisation’s content or services.

Public sources, corrections and sensitive information

Commentary about organisations and incidents is based on information believed to be lawfully available, such as official notices, public reporting and published guidance. It is not intended to reveal confidential information or describe the non-public security posture of an employer, client or other organisation.

If you believe an article contains a material factual error, exposes information that should not be public, or requires important context, email [email protected]. Corrections will be considered on their merits.

Copyright and permission to reuse

Unless a page expressly states otherwise, all original text, photographs, diagrams and other site content are copyright Nicholas O’Sullivan. Site content may be reused only with Nicholas’s prior written permission, except to the extent that reuse is permitted by law.

Brief quotations with clear attribution and a link to the original page are welcome where permitted by law. For any other reproduction, adaptation, republication, commercial use or distribution, request permission at [email protected].

Third-party trademarks and material remain the property of their respective owners and may be subject to separate licences or permissions.
